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.

782,773,072 = 24 x 5,2331 x 9,3491
Down Arrow
d(n) = (a + 1)(b + 1)(c + 1)
Down Arrow
d(782773072) = (4 + 1)(1 + 1)(1 + 1)
Down Arrow
d(782773072) = (5)(2)(2)
Down Arrow
d(782773072) = 20
