Greatest Common Factor

We found the factors 400,820,127 . The biggest common factor number is the GCF number.
So the greatest common factor 400,820,127 is 1.

Lets's calculate LCM of 70,92,390

2 70, 92, 390
5 35, 46, 195
7, 46, 39

∴ So the LCM of the given numbers is 2 x 5 x 7 x 46 x 39 = 125580

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/125580

Therefore, the GCF of Fractions 400/70,820/92,127/390 is 1/125580

Least Common Multiple of 70,92,390 with GCF Formula

Least Common Multiple of 70,92,390 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 70,92,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,92,390) = 2

common factors(in case of two or more numbers have common factors) = 10

GCF(70,92,390) x common factors =2 x 10 = 20

LCM(70,92,390) = ( 70 × 92 × 390 ) / 20

LCM(70,92,390) = 2511600 / 20

LCM(70,92,390) = 125580
