How do you find the greatest number of four digit that is divisible by 936 and 45 by finding the HCF?

It is easier to find the lowest common number, then getting the largest multiple of that that is under 10000. The LCM is 4680, x2 is 9360.

There are 278 5-digit numbers less than 20,000 that are divisible by both four and nine.


What are the steps for least common multiple?

We want to express any number as multiples of numbers under 10, and as close to 0, if possible. The number 13, for example, can't be divided any more. It is called a PRIME number. So a number like 26, which is reduced to 2 x 13, is as far as you can go. 2. A number is divisible by 2 if its right-hand digit is even. 3. A number is divisible by 3 if the sum of its digits is divisible by 3. For example, the digits of the number 6,561 add to produce the sum 18. Since 18 is divisible by 3, we know that 6,561 is divisible by 3. 4. A number is divisible by 4 if the number formed by the two right-hand digits is divisible by 4. For example, the two right-hand digits of the number 3,524 form the number 24. Since 24 is divisible by 4, we know that 3,524 is divisible by 4. 5. A number is divisible by 5 if its right-hand digit is 0 or 5. 6. A number is divisible by 6 if it is even and the sum of its digits is divisible by 3. For example, the sum of the digits of 64,236 is 21, which is divisible by 3. Since 64,236 is also an even number, we know that it is divisible by 6. 7. No short method has been found for determining whether a number is divisible by 7. 8. A number is divisible by 8 if the number formed by the three right-hand digits is divisible by 8. For example, the three right-hand digits of the number 54,272 form the number 272, which is divisible by 8. Therefore, we know that 54,272 is divisible by 8. 9. A number is divisible by 9 if the sum of its digits is divisible by 9. For example, the sum of the digits of 546,372 is 27, which is divisible by 9. Therefore we know that 546,372 is divisible by 9.


What is a 3 digit number that is even a square number under 500 and it's sum of digits is divisable by 15?

the squares of 10 though 22 are all three digit numbers under 500. though none of the sums of their digits total an even multiple of 15.

What are the Divisibility rules of 14 15 18?

14...Checking for divisibility by 14 would combine the rules for 2 and 7, since 2x7 = 14The rule for 2 is that the last digit of the number is even (0,2,4,6 or 8).There is no real rule for 7, but there is one way of testing divisibility by 7 that I have come up with, although rather complicated. First, write your number, then beneath it, under each digit from right to left, write out the numbers 1,3,2,6,4,5 in that order and keep repeating the sequence until each digit of your number has another digit beneath it. Use only the amount of digits needed. Then, multiply each digit of your number by the digit beneath it, and add all of these new numbers. If the number you get is a multiple of 7, the number you began with was also a multiple of 7.Example for 7:We are checking 3192847 for divisibility by 7...3 1 9 2 8 4 71 5 4 6 2 311x3 + 5x1 + 4x9 + 6x2 + 2x8 + 3x4 + 1x7= 3 + 5 + 36 + 12 + 16 + 12 + 791We can test 91 again to find divisibility...9 13 13x9 + 1x1 = 2828 is a multiple of 7 (it is 4 x 7), so 91 and 3192847 must also be multiples of 7. 3192847 is actually 456121 x 7.If both of these tests work, the number must be a multiple of 14.15...Divisibility by 15 can be tested by combining the rules for 3 and 5.The rule for 3 is that the sum of all the digits in the number is a multiple of 3.The rule for 5 is that the number ends in 5 or 0.If both of these tests work, the number must be a multiple of 15.18...Checking for divisibility by 18 combines the divisibility rules for 2 and 9.Once again, a number is divisible by 2 if its last digit is even.A number is divisible by 9 if the sum of its digits is a multiple of 9.If both of these tests work, the number must be divisible by 18.

Is the product of a 4-digit number and a 1-digit number always a 5-digit number Explain?

This is not true. Think about any 4 digit multiplied by 1. This remains a 4 digit. In the case of any 4 digit under 5000, multiplied by two would also be a 4 digit number

how many different counting numbers less than 200 are exactly divisible by either 6 or 9 or both?

According to a source, there are 44 counting numbers less than 200 that are exactly divisible by either 6 or 9, or by both. To determine the total count, we can follow these steps: Find out how many counting numbers less than 200 are divisible by 6. The last number under 200 that is divisible by 6 is 198, and since 198 is the 33rd multiple of 6, there are 33 such numbers. Next, figure out how many numbers are divisible by 9. The last number under 200 that is divisible by 9 is also 198, and since 198 is the 22nd multiple of 9, there are 22 such numbers. Some numbers will be divisible by both 6 and 9, but we need to avoid counting these twice. So, determine which numbers are divisible by both (these are actually multiples of 18). The last number under 200 that is divisible by 18 is also 198, and since it is the 11th multiple of 18, there are 11 such numbers. Finally, add the two individual counts from steps 1 and 2 together and subtract the count from step 3 to eliminate double counting: 33 + 22 - 11 = 44. Therefore, there are 44 different counting numbers less than 200 that are exactly divisible by either 6 or 9 or both.


What is the Largest number under 120 that is divisible by 11 and 8?

88 = 8x11 For the number to be divisible by both 8 and 11 it must be a multiple of their product (since 11 is prime 8, being smaller, shares no factors with it). You can't multiply 8x11 by any integer smaller than 2 (not counting 1 of course). Multiplying by the next integer - 2 - produces a number bigger than 120
