How do you find how many proper divisors 7920 has?
To find the number of divisors of a number, factor it into primes in power format; then the number of factors the number has is the product of the powers of the primes each incremented by 1. To find the proper divisors subtract one from thin number. The prime factorization of 7920 is 2^4 x 3^2 x 5 x 11, so it has (4 + 1) × (2 + 1) × (1 + 1) × (1 + 1) = 5 × 3 × 2 × 2 = 60 factors. As this includes the number itself and the proper factors of a number exclude the number, 7920 has 60 - 1 = 59 proper factors (divisors).

How many miles are there in 7920 feet?
There are 5280 feet in one mile. Therefore, 7920 feet is equal to 7920 / 5280 = 1.5 miles.
What is the term for equal to the sum of its proper factors?
A perfect number is the term for a number that is equal to the sum of its proper divisors. Be careful not to confuse that with proper factors. Proper divisors include 1 but not the number itself. Proper factors don't include either I or the original number.
Is 19 composite?
no- 19 is prime which means it has no proper divisors.
