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
The greatest common factor of 52 and 81 is 1
115.71%% rate:= 81/70 * 100%= 1.1571 * 100%= 115.71%
Divide 81 by 70%. ===> That is, solve the problem: (81) / (0.7)
81
