∙ 9y agoAdd together all the factors of a number, apart from itself.
If the answer is less than the number, then it is deficient.
If the answer is equal to the number, then it is perfect.
If the answer is greater than the number, then it is abundant.
The factors of 8 are 1, 2 and 4. 1+2+4 = 7 so 8 is deficient.
The factors of 6 are 1, 2 and 3. 1+2+3 = 6 so 6 is perfect.
The factors of 12 are 1, 2, 3, 4 and 6. 1+2+3+4+6 = 16 so 12 is abundant.
