what is the prime factorization of : 1479 and 4403?

Answer 1

PROBLEM 1:

1479 (digits add to multiple of 3), so 3 is a factor:

1479 / 3 = 493
493 / 17 = 29
29 is prime

Therefore 1479 = 3 x 17 x 29

PROBLEM 2:

4403 (2, 3 and 5 are not factors, but 7 is):

4403 / 7 = 629
629 / 17 = 37
37 is prime

Therefore 4403 = 7 x 17 x 37

And in case it is relevant:
Greatest common factor (GCF) is 17
Lowest common multiple (LCM) is 3 x 7 x 17 x 29 x 37 = 383,061
