If the number formed by the last three digits is divisible by 8. This requires that: if the digit in the hundreds place is even, the last two digits must form a number divisible by 8 and if the digit in the hundreds place is odd, the last two digits must form a number divisible by 4 but not by 8.

2,4,6,8,and 0 are divisible by 2 in the ones digit. Zero is only divisible in a number with 2 digits or more. 0 itself is not divisible by 2.

To know if a number is composite without listing its factors, you can use these rules:All numbers that end with 2, 4, 6, 8, and 0 (even numbers) are divisible by 2.If the sum of the digits in a number is divisible by 3, the number is divisible by 3.If the last two digits are divisible by 4, the number is divisible by 4.All numbers that have 5 in the one's place are divisible by 5.If a number is divisible by 2 AND is divisible by 3, it is divisible by 6.If the last 3 digits of a number are divisible by 8, the number is divisible by 8.If the sum of the digits of number is divisible by 9, the number is divisible by 9.If a number ends wuth 0, the number is divisible by 10.

Sol. Since the given number is divisible by 5, so 0 or 5 must come in place of $. But, a number ending with 5 is never divisible by 8. So, 0 will replace $. Now, the number formed by the last three digits is 4*0, which becomes divisible by 8, if * is replaced by 4. Hence, digits in place of * and $ are 4 and 0 respectively.

102 is divisible by 2,3 and 6 A number is divisible by 2 if the number has even number on its unit place. A number is divisible by 3 if the sum of all the digits of the number is divisible by 3. For example= In number 102 1+0+2=3 and yes it is divisible by 3 A number is divisible by 6 if it is divisible by both 2 and 3 These laws of divisibility are applicable everywhere.

Since 6 = 2 x 3, in order for a number to be evenly divisible by 6, it needs to be divisible by 3 and divisible by 2. 1197 is divisible by 3 (by inspection of sum of digits), but it is not divisible by 2 (the ones place digit must be 0,2,4,6, or 8)

For a number to be divisible by both 8 and 5 then : 1) the final digit must be zero (as a multiple of 5 ending in 5 is not divisible by 8) 2) As 1000 is divisible by 8 then only the last 3 digits of the number need to be checked to confirm if it is divisible by 8. 680 ÷ 8 = 85. Therefore the number has to be changed to 62680 to be divisible by both 8 and 5. Therefore, replace the digit 4 in 62684 with 0.

You test if the last two digits are divisible by 4. If the digit in the tens' place is odd, the digit in the units place must be 2 or 6. If the digit in the tens' place is even, the digit in the units place must be 0, 4 or 8.

Are you asking what the divisibility rule for 4 is?===========A number is divisible by 5 if it ends in a 0 or a 5=====There are two ways to test for divisibility by 4.A number is divisible by 4 if it is divisible by 2 twice. That is, the factor you get when you factor a 2 out must also be divisible by 2.Example... is 516 divisible by 4?Well, is it divisible by 2? Yes, it is even. Factor that 2 out you get 258. Is 258 also divisible by 2? Yes, it too is even. Since it was divisible by 2 and the quotient was also divisible by 2 then the original was divisible by 4.But, 4's have another rule that is simpler.All you have to do is look at the smallest two digits: the ones and tens place. You can ignore anything in the hundreds place or up. If the ones and tens place form a number that is divisible by 4 then the whole number is also divisible by 4Example: Is 52848474116 divisible by 4?Just take the last two digits off and test them. 16. Is 16 divisible by 4? Yes, so that whole mess of a number is also.

No; for a number to be divisible by 10, the last number (ones place) must be zero.

Divisibility RulesA number is divisible by another number if it can be divided equally by that number; that is, if it yields a whole number when divided by that number. For example, 6 is divisible by 3 (we say "3 divides 6") because 6/3 = 2 , and 2 is a whole number. 6 is not divisible by 4, because 6/4 = 1.5 , and 1.5 is not a whole number. It is often useful to know whether a number divides another number. To check divisibility, one can always do the division out by hand and see if the result is a whole number. However, if the number we are dividing is large, this becomes very difficult. There are some divisibility rules which make this task much easier--these rules allow us to determine whether a number is divisible by another number without having to carry out the division.Divisibility by 1A number does not change when it is divided by 1. Therefore, every whole number is divisible by 1.Divisibility by 2, 4, and 8All even numbers are divisible by 2. Therefore, a number is divisible by 2 if it has a 0, 2, 4, 6, or 8 in the ones place. For example, 54 and 2,870 are divisible by 2, but 2,221 is not divisible by 2.A number is divisible by 4 if its last two digits are divisible by 4. For example, 780, 52, and 80,744 are divisible by 4, but 7,850 is not divisible by 4. To check whether a number is divisible by 4, just divide the last two digits of the number by 4. If the result is a whole number, then the original number is divisible by 4.A number is divisible by 8 if its last three digits are divisible by 8. For example, 880 and 905,256 are divisible by 8 but 74,513 is not divisible by 8. To check divisibility by 8, divide the last three digits of the number by 8. If the result is a whole number, then the original number is divisible by 8.Divisibility by 3, 6, and 9A number is divisible by 3 if its digits add up to a number divisible by 3. For example, 671,451 is divisible by 3 because 6 + 7 + 1 + 4 + 5 + 1 = 24 , and 24 is divisible by 3. 84,950 is not divisible by 3, because 8 + 4 + 9 + 5 + 0 = 26 , and 26 is not divisible by 3.A number is divisible by 6 if it is divisible by 2 and 3. In other words, a number is divisible by 6 if its digits add up to a number divisible by 3 and it ends with an even number. 671,451 (our previous example) is divisible by 3, but not by 2, because 1 is not an even number. Therefore, 671,451 is not divisible by 6. On the other hand, 789,312 is divisible by 6, because 7 + 8 + 9 + 3 + 1 + 2 = 30 , which is divisible by 3, and its last digit is 2, which is even.A number is divisible by 9 if its digits add up to a number divisible by 9. For example, 91,458 is divisible by 9 because 9 + 1 + 4 + 5 + 8 = 27 and 27 is divisible by 9. 18,453 is not divisible by 9 because 1 + 8 + 4 + 5 + 3 = 21 and 21 is not divisible by 9.Divisibility by 5A number is divisible by 5 if it ends in 0 or 5. For example, 875 and 600 are divisible by 5, but 76,508 is not divisible by 5.Divisibility by 10A number is divisible by 10 if it ends in 0. For example, 65,110 and 90 are divisible by 10, but 6,007 is not divisible by 10.Note: Because a number divided by itself always yields 1, a number is always divisible by itself. For example, 7 is divisible by 7 and 8,374 is divisible by 8,374.Note: No number is divisible by a number greater than itself.

240 is three digits, and has a '2' in the hundreds column. 240/3 = 80 240/4 = 60 240/5 = 48
