Lets's calculate LCM of 45,30,119

3 45, 30, 119
5 15, 10, 119
3, 2, 119

∴ So the LCM of the given numbers is 3 x 5 x 3 x 2 x 119 = 10710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10710

Therefore, the GCF of Fractions 30/45,43/30,178/119 is 1/10710

Least Common Multiple of 45,30,119 with GCF Formula

Least Common Multiple of 45,30,119 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 45,30,119 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,30,119) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(45,30,119) x common factors =1 x 15 = 15

LCM(45,30,119) = ( 45 × 30 × 119 ) / 15

LCM(45,30,119) = 160650 / 15

LCM(45,30,119) = 10710
