So the greatest common factor 396,453,100 is 1.

Lets's calculate LCM of 70,98,780

2 70, 98, 780
5 35, 49, 390
7 7, 49, 78
1, 7, 78

∴ So the LCM of the given numbers is 2 x 5 x 7 x 1 x 7 x 78 = 38220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38220

Therefore, the GCF of Fractions 396/70,453/98,100/780 is 1/38220

Least Common Multiple of 70,98,780 with GCF Formula

Least Common Multiple of 70,98,780 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 70,98,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,98,780) = 2

common factors(in case of two or more numbers have common factors) = 70

GCF(70,98,780) x common factors =2 x 70 = 140

LCM(70,98,780) = ( 70 × 98 × 780 ) / 140

LCM(70,98,780) = 5350800 / 140

LCM(70,98,780) = 38220
