Factor Tree

	111,171,502

2		55,585,751

	13		4,275,827

		89		48,043

			107		449

The prime factorization in exponential form is: 2¹ x 13¹ x 89¹ x 107¹ x 449¹

Step 2

Setup the equation for determining the number of factors or divisors. The equation is:

d(n) = (a + 1)(b + 1)(c + 1)(d + 1)(e + 1)

Where d(n) is equal to the number of divisors of the number and a, b, etc. are equal to the exponents of the prime factorization.

Now substitute the letters in the equation with the the exponents of your prime factorization and then solve to calculate the total number of divisors.

111,171,502 = 2¹ x 13¹ x 89¹ x 107¹ x 449¹

d(n) = (a + 1)(b + 1)(c + 1)(d + 1)(e + 1)

d(111171502) = (1 + 1)(1 + 1)(1 + 1)(1 + 1)(1 + 1)

d(111171502) = (2)(2)(2)(2)(2)

d(111171502) = 32
