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.

20,555,456 = 26 x 5091 x 6311
Down Arrow
d(n) = (a + 1)(b + 1)(c + 1)
Down Arrow
d(20555456) = (6 + 1)(1 + 1)(1 + 1)
Down Arrow
d(20555456) = (7)(2)(2)
Down Arrow
