is 700 divisible by 4?
Yes, 700 is divisible by 4. To check whether a number is divisible by 4, just divide the last two digits of the number by 4. When we check: 700÷4 = 175 Therefore, Yes :)
What a number between 400 and 500 that is divisible by 3 not 2?
To find out if a number is divisible by 3 add up all it's digest and check if the total is divisible by 3. to check if a number is divisible by 2 check if the last digit is divisible by 2. So one such number is 405.
How do you find prime numbers between 2 and 70?
You can check each individual number, whether it is a prime number. For numbers below 100, it is enough to check whether they are divisible by 2, by 3, by 5, and by 7. If a number is divisible by none of these, it is a prime number.
What is 289 divisible by?
No, 288 is, but 289 is not. For a number "x" to be divisible by 4, "x" must be even, and "x/2" must be even as well. 289 is not even. ■ To check whether or not the number is divisible by 4 it is enough to check (as above) that the last two digits of the number are divisible by 4. In this case, it would be to check that 89 is divisible by 4.
What is a trick to see if a number is divisble by 4?
It is enough to check whether the last two digits are divisible by 2.
If the last digit of a number is 6 then is 6 a factor?
Not necessarily. For example, the number 56 ends in a 6 but is not divisible by six. To check if a number is divisible by six, the number must be divisible by both 2 and 3. To check this, the last digit must be even and the sum of the digits must be divisible by three. If the number meets these conditions, it is in fact divisible by six.
How do you know if a number is divisible by 6?
Quickly check to see whether it's divisible by both 2 and 3. Here's how to do that easily: -- The number is divisible by 2 if it's an even number . . . the last digit is 2, 4, 6, 8, or 0. -- The number is divisible by 3 if the sum of its digits is divisible by 3.
What does it mean when one number is divisable by another number?
When one number is divisible by another number, it means that the first number can be divided by the second number without leaving a remainder. In other words, the division operation results in a whole number without any fraction.
What is 120603 divisible to?
To determine if 120,603 is divisible by a certain number, we need to check if the number divides evenly into 120,603 without leaving a remainder. To do this, we can perform a division operation. For example, to check if 120,603 is divisible by 3, we would divide 120,603 by 3 and see if the result is a whole number. If the division result is a whole number, then 120,603 is divisible by that number.
How do you solve prime and composite numbers?
That depends what you need to "solve". If what you want to do is check whether a number is prime or composite, check whether it is divisible by 2, and then by all odd numbers up to the square root of your number. For example, for numbers up to 120, you only need to check whether they are divisible by 2, 3, 5, 7 (9 is composite, so you don't really need to check divisibility by 9). If your number is divisible by any such number, then it is composite; otherwise it is a prime. There are more efficient methods, but they are also more complicated, and it really only makes sense to use them for much larger numbers.
a number divisible by 5 and 10?
73540 For example, let us check if the number 73540 is divisible by 5 and 10. The last digit in the given number is 0, hence, 73540 is divisible by 5. The same condition is satisfied for the divisibility rule of 10 since the last digit is zero. Therefore, 73540 is divisible by 5 as well as 10.
Determine if a number is divisible by 3?
Check the sum of the digits, if the sum divisible by 3 then the number is divisible by 3. Example 910: the sum of digits= 9 + 1 + 0 = 10, but 10 is not divisible by 3, so the number 910 is not divisible by 3. Example 2154: the sum of digits = 2 + 1 + 5 + 4 = 12, this sum is divisible by 3, so the number 2154 is divisible by 3. if the sum is long you can check the sum of the sum and apply the same rule. Example 52498731: the sum of digits = 5 + 2 + 4 + 9 + 8 + 7 + 3 + 1 = 39, the sum of the digits for 39 = 3 + 9 = 12, so the original number, i.e. 52498731 is divisible by 3.
