LCM of:

Least Common Multiple of 61/72,756/51,836/18

Given numbers are 61/72,756/51,836/18

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 61,756,836

Least Common Multiple of Numerators i.e. LCM of 61,756,836 is 9638244.

GCF of Denominators means GCF of 72,51,18 as per the given fractions.

GCF of 72,51,18 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 61,756,836

LCM of Fractions 61/72,756/51,836/18 is 3212748

2 61, 756, 836
2 61, 378, 418
61, 189, 209

∴ So the LCM of the given numbers is 2 x 2 x 61 x 189 x 209 = 9638244

Least Common Multiple of 61,756,836 with GCF Formula

Least Common Multiple of 61,756,836 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 61,756,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,756,836) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(61,756,836) x common factors =1 x 4 = 4

LCM(61,756,836) = ( 61 × 756 × 836 ) / 4

LCM(61,756,836) = 38552976 / 4

LCM(61,756,836) = 9638244


Lets's calculate GCF of 72,51,18

3 72, 51, 18
24, 17, 6

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9638244/3

Therefore the LCM of Fractions 61/72,756/51,836/18 is 3212748
