Lets's calculate LCM of 77,40,970

2 77, 40, 970
5 77, 20, 485
77, 4, 97

∴ So the LCM of the given numbers is 2 x 5 x 77 x 4 x 97 = 298760

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/298760

Therefore, the GCF of Fractions 55/77,31/40,911/970 is 1/298760

Least Common Multiple of 77,40,970 with GCF Formula

Least Common Multiple of 77,40,970 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 77,40,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,40,970) = 1

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

GCF(77,40,970) x common factors =1 x 10 = 10

LCM(77,40,970) = ( 77 × 40 × 970 ) / 10

LCM(77,40,970) = 2987600 / 10

LCM(77,40,970) = 298760
