Greatest Common Factor

We found the factors 64,63,80,45 . The biggest common factor number is the GCF number.
So the greatest common factor 64,63,80,45 is 1.

Lets's calculate LCM of 77,74,15,48

2 77, 74, 15, 48
3 77, 37, 15, 24
77, 37, 5, 8

∴ So the LCM of the given numbers is 2 x 3 x 77 x 37 x 5 x 8 = 683760

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/683760

Therefore, the GCF of Fractions 64/77,63/74,80/15,45/48 is 1/683760

Least Common Multiple of 77,74,15,48 with GCF Formula

Least Common Multiple of 77,74,15,48 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 77,74,15,48 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,74,15,48) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(77,74,15,48) x common factors =1 x 6 = 6

LCM(77,74,15,48) = ( 77 × 74 × 15 × 48 ) / 6

LCM(77,74,15,48) = 4102560 / 6

LCM(77,74,15,48) = 683760
