We have been enjoying exploring Abundant Numbers- have a go yourselves…

To find the factors of a number, you have to find all the pairs of numbers that multiply together to give that number.

The factors of 48 are:

1 and 48

2 and 24

3 and 16

4 and 12

6 and 8

If we leave out the number we started with, 48, and add all the other factors, we get 76:

1+2+3+4+6+8+12+16+24=76

So …. 48 is called an abundant number because it is less than the sum of its factors (without itself). (48 is less than 76.)

See if you can find some more abundant numbers!
