In what diffrent ways can 440 be written as the product of two positve integers

440 = 1 x 2 x 2 x 2 x 5 x 11

(1) : 1 x 440

(2) : 2 x 220

(2 x 2) : 4 x 110

(5) : 5 x 88

(2x2x2) : 8 x 55

(2 x 5) : 10 x 44

(11) : 11 x 40

(2x2x5) : 20 x 22

No need to continue because the next number is 2 x 11 = 22 and we already have that on the right side, so we have found all of the multiplicative pairs of 440.
