Whole Numbers- Factors
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!
