Factor Tree

	281,418,547

23		12,235,589

	41		298,429

		167		1,787

The prime factorization in exponential form is: 23¹ x 41¹ x 167¹ x 1,787¹

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)

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.

281,418,547 = 23¹ x 41¹ x 167¹ x 1,787¹

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

d(281418547) = (1 + 1)(1 + 1)(1 + 1)(1 + 1)

d(281418547) = (2)(2)(2)(2)

d(281418547) = 16
