LCM of:

Least Common Multiple of 42/29,70/836,490/516

Given numbers are 42/29,70/836,490/516

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 42,70,490

Least Common Multiple of Numerators i.e. LCM of 42,70,490 is 1470.

GCF of Denominators means GCF of 29,836,516 as per the given fractions.

GCF of 29,836,516 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,70,490

LCM of Fractions 42/29,70/836,490/516 is 1470

2 42, 70, 490
5 21, 35, 245
7 21, 7, 49
3, 1, 7

∴ So the LCM of the given numbers is 2 x 5 x 7 x 3 x 1 x 7 = 1470

Least Common Multiple of 42,70,490 with GCF Formula

Least Common Multiple of 42,70,490 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 42,70,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,70,490) = 14

common factors(in case of two or more numbers have common factors) = 70

GCF(42,70,490) x common factors =14 x 70 = 980

LCM(42,70,490) = ( 42 × 70 × 490 ) / 980

LCM(42,70,490) = 1440600 / 980

LCM(42,70,490) = 1470


Lets's calculate GCF of 29,836,516

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1470/1

Therefore the LCM of Fractions 42/29,70/836,490/516 is 1470
