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.

278,847,872 = 27 x 171 x 128,1471
Down Arrow
d(n) = (a + 1)(b + 1)(c + 1)
Down Arrow
d(278847872) = (7 + 1)(1 + 1)(1 + 1)
Down Arrow
d(278847872) = (8)(2)(2)
Down Arrow
d(278847872) = 32
