Least Common Multiple (LCM) for 71 81 is 5,751
87.65%% rate:= 71/81 * 100%= 0.8765 * 100%= 87.65%
71 and 81 are coprime so the only common factor is 1.
It is 1
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
