OK, here's a big critter!

Find the prime factorization of 1848:


1848 is even and splits into 2 and 924  ...  924 is even too and splits into 2 and 462  ...  462 is even too and splits into 2 and 231  ...  231 splits into 3 and 77  ...  77 splits into 7 and 11  ...  Remember your divisibility tests!

 

1848 = 2 x 2 x 2 x 3 x 7 x 11

1848 = 2^2 x 3 x 7 x 11
