So the greatest common factor 8,45,12,357 is 1.

Lets's calculate LCM of 40,69,680,652

2 40, 69, 680, 652
2 20, 69, 340, 326
2 10, 69, 170, 163
5 5, 69, 85, 163
1, 69, 17, 163

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 69 x 17 x 163 = 7647960

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7647960

Least Common Multiple of 40,69,680,652 with GCF Formula

Least Common Multiple of 40,69,680,652 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 40,69,680,652 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,69,680,652) = 1

common factors(in case of two or more numbers have common factors) = 160

GCF(40,69,680,652) x common factors =1 x 160 = 160

LCM(40,69,680,652) = ( 40 × 69 × 680 × 652 ) / 160

LCM(40,69,680,652) = 1223673600 / 160

LCM(40,69,680,652) = 7647960
