2 x 2 x 2 x 3 x 7 = 8 x 21 = 168
22 x 7
33 ft.
3 x 29 = 87
78 = 2 * 3 * 13
2 x 2 x 2 x 3 x 7 = 8 x 21 = 168
1450 as a product of primes = 2 * 5 * 5 * 29
5x5x3
20 as a product of primes = 2 * 2 * 5
5*3
2 * 33 * 72
168=2*2*2*7*32 x 2 x 2 x 3 x 7
2*2*2*5*!
14 = 2 x 7
It is: 7 times 13 = 91
22 = 2 x 11
