Lets's calculate LCM of 66,220,792

2 66, 220, 792
2 33, 110, 396
3 33, 55, 198
11 11, 55, 66
1, 5, 6

∴ So the LCM of the given numbers is 2 x 2 x 3 x 11 x 1 x 5 x 6 = 3960

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3960

Therefore, the GCF of Fractions 61/66,77/220,310/792 is 1/3960

Least Common Multiple of 66,220,792 with GCF Formula

Least Common Multiple of 66,220,792 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 66,220,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,220,792) = 22

common factors(in case of two or more numbers have common factors) = 132

GCF(66,220,792) x common factors =22 x 132 = 2904

LCM(66,220,792) = ( 66 × 220 × 792 ) / 2904

LCM(66,220,792) = 11499840 / 2904

LCM(66,220,792) = 3960
