Lets's calculate LCM of 438,400,940

2 438, 400, 940
2 219, 200, 470
5 219, 100, 235
219, 20, 47

∴ So the LCM of the given numbers is 2 x 2 x 5 x 219 x 20 x 47 = 4117200

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4117200

Therefore, the GCF of Fractions 79/438,85/400,699/940 is 1/4117200

Least Common Multiple of 438,400,940 with GCF Formula

Least Common Multiple of 438,400,940 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 438,400,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(438,400,940) = 2

common factors(in case of two or more numbers have common factors) = 20

GCF(438,400,940) x common factors =2 x 20 = 40

LCM(438,400,940) = ( 438 × 400 × 940 ) / 40

LCM(438,400,940) = 164688000 / 40

LCM(438,400,940) = 4117200
