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.

85,506,813 = 33 x 74 x 1,3191
Down Arrow
d(n) = (a + 1)(b + 1)(c + 1)
Down Arrow
d(85506813) = (3 + 1)(4 + 1)(1 + 1)
Down Arrow
d(85506813) = (4)(5)(2)
Down Arrow
