how many factors 720 has

To find the number of factors of 720, we first need to express 720 as a product of its prime factors.

720 = 2^4 * 3^2 * 5^1

The number of factors of a number is determined by adding 1 to each of the exponents in the prime factorization and then multiplying these results together.

So, the number of factors of 720 is (4+1) * (2+1) * (1+1) = 5 * 3 * 2 = 30.

Therefore, 720 has 30 factors.
