The prime factorization in exponential form is: 33 x 71 x 171 x 6,2871

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.

20,200,131 = 33 x 71 x 171 x 6,2871
Down Arrow
d(n) = (a + 1)(b + 1)(c + 1)(d + 1)
Down Arrow
d(20200131) = (3 + 1)(1 + 1)(1 + 1)(1 + 1)
Down Arrow
d(20200131) = (4)(2)(2)(2)
Down Arrow
d(20200131) = 32
