Lets's calculate LCM of 11,77,980

7 11, 77, 980
11 11, 11, 140
1, 1, 140

∴ So the LCM of the given numbers is 7 x 11 x 1 x 1 x 140 = 10780

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10780

Therefore, the GCF of Fractions 80/11,75/77,421/980 is 1/10780

Least Common Multiple of 11,77,980 with GCF Formula

Least Common Multiple of 11,77,980 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 11,77,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(11,77,980) = 1

common factors(in case of two or more numbers have common factors) = 77

GCF(11,77,980) x common factors =1 x 77 = 77

LCM(11,77,980) = ( 11 × 77 × 980 ) / 77

LCM(11,77,980) = 830060 / 77

LCM(11,77,980) = 10780
