Factor Tree

	160,718,493

3		53,572,831

	13		4,120,987

		13		316,999

			17		18,647

				29		643

The prime factorization in exponential form is: 3¹ x 13² x 17¹ x 29¹ x 643¹

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.

160,718,493 = 3¹ x 13² x 17¹ x 29¹ x 643¹

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

d(160718493) = (1 + 1)(2 + 1)(1 + 1)(1 + 1)(1 + 1)

d(160718493) = (2)(3)(2)(2)(2)

d(160718493) = 48
