48 is divisible by 2, 3, 4, 6, 8, 12, 16, 24 and 48 Perfect --a number is perfect if the sum of the factors less than the number is equal to the number ( The factors of 28 are 1, 2, 4, 7, and 14. The sum of these factors is 28). Abundant – a number is abundant if the sum of the factors less than the number is greater than the number.(12 is an abundant number). Deficient – sum of factors
is less than the number (10 is a deficient number). Prime – a number having only 2 factors, itself and 1. Composite – a number with more than two factors.
