Is 3 a factor of 261 and why?

Answer 1

To determine if 3 is a factor of 261, we need to check if 261 is divisible by 3 without any remainder. We can do this by dividing 261 by 3. When we divide 261 by 3, we get 87 with no remainder. Therefore, 3 is a factor of 261 because it divides evenly into 261.

Answer 2

Well, isn't that just a happy little question! Let's take a closer look at 261. If a number is a factor of another number, it means it divides evenly into it without leaving a remainder. So, if we divide 261 by 3, we get 87, which means yes, 3 is indeed a factor of 261. Just like painting a beautiful landscape, mathematics can be quite magical when you step back and see the whole picture.

Answer 3

Yes, because the digits of 261 add up to a multiple of 3.

Answer 4

Yes, an easy way to find out if anything is a factor of three is to add up all the digits. For example, 2+6+1 = 9. If that sum is a multiple of 3, your original factor is too.

Answer 5

No, 3 is not a factor of 61.

Answer 6

No.
