Lets's calculate LCM of 45,866,639

LCM of Fractions 45/140,866/744,639/424 is 2766870/4

3 45, 866, 639
3 15, 866, 213
5, 866, 71

∴ So the LCM of the given numbers is 3 x 3 x 5 x 866 x 71 = 2766870

Least Common Multiple of 45,866,639 with GCF Formula

Least Common Multiple of 45,866,639 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 45,866,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,866,639) = 1

common factors(in case of two or more numbers have common factors) = 9

GCF(45,866,639) x common factors =1 x 9 = 9

LCM(45,866,639) = ( 45 × 866 × 639 ) / 9

LCM(45,866,639) = 24901830 / 9

LCM(45,866,639) = 2766870


Lets's calculate GCF of 140,744,424

2 140, 744, 424
2 70, 372, 212
35, 186, 106

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2766870/4

Therefore the LCM of Fractions 45/140,866/744,639/424 is 2766870/4
