84 = 2*2*3*7
The prime factors of 72 are 2 and 3.
2 x 2 x 2 x 2 x 3
56 = 2 x 2x 2 x 7 56 = 23 x 7
64 = 2 x 2 x 2 x 2 x 2 x 2 or 26
64 = 2 x 2 x 2 x 2 x 2 x 2 or 26
Express 84 in terms of its prime factors. 84 = 2 x 2 x 3 x 7 = 22 x 3 x 7 As 12 = 22 x 3, then the remaining factor is 7 so 84 ÷ 12 = 7 As 21 = 3 x 7, then the remaining factors are 22 (= 4) so 84 ÷ 21 = 4
