The Prime Factorization for 70 is 7 x 5 x 2
2 x 5 x 7 = 70
Looks like 70, 490 = 7 x 70, 630 = 9 x 70 and 7 and 9 are co-prime.
140 = 2 * 2 * 5 * 7 700 = 2 * 2 * 5 * 5 * 7
For 70 it is: 2, 5 and 7 For 90 it is: 2, 3, 3 and 5
2 x 5 x 7 = 70

Method of prime factorization is one of the best methods to find L.C.M. Prime factorization of 81 = 3x3x3x3 Prime factorization of 70 = 2x5x7 It is clear that nothing is common in Prime Factorization of both numbers. Also, L.C.M. = Product of common numbers x Product of uncommon factors So, L.C.M. of 81 and 70 = Product of 81 and 70(Because nothing is common in 71 and 80) = 81 x 70 = 5670
