Lets's calculate LCM of 80,77,40,390

2 80, 77, 40, 390
2 40, 77, 20, 195
2 10, 77, 20, 195
5 5, 77, 10, 195
1, 77, 2, 39

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 77 x 2 x 39 = 240240

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/240240

Therefore, the GCF of Fractions 73/80,73/77,69/40,42/390 is 1/240240

Least Common Multiple of 80,77,40,390 with GCF Formula

Least Common Multiple of 80,77,40,390 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 80,77,40,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,77,40,390) = 1

common factors(in case of two or more numbers have common factors) = 400

GCF(80,77,40,390) x common factors =1 x 400 = 400

LCM(80,77,40,390) = ( 80 × 77 × 40 × 390 ) / 400

LCM(80,77,40,390) = 96096000 / 400

LCM(80,77,40,390) = 240240
