Least Common Multiple of 81/97,95/31,18/14,72/33

Given numbers are 81/97,95/31,18/14,72/33

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 81,95,18,72

Least Common Multiple of Numerators i.e. LCM of 81,95,18,72 is 61560.

GCF of Denominators means GCF of 97,31,14,33 as per the given fractions.

GCF of 97,31,14,33 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,95,18,72

LCM of Fractions 81/97,95/31,18/14,72/33 is 61560

2 81, 95, 18, 72
3 81, 95, 9, 36
3 27, 95, 3, 12
9, 95, 1, 4

∴ So the LCM of the given numbers is 2 x 3 x 3 x 9 x 95 x 1 x 4 = 61560

Least Common Multiple of 81,95,18,72 with GCF Formula

Least Common Multiple of 81,95,18,72 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 81,95,18,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,95,18,72) = 1

common factors(in case of two or more numbers have common factors) = 162

GCF(81,95,18,72) x common factors =1 x 162 = 162

LCM(81,95,18,72) = ( 81 × 95 × 18 × 72 ) / 162

LCM(81,95,18,72) = 9972720 / 162

LCM(81,95,18,72) = 61560


Lets's calculate GCF of 97,31,14,33

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 61560/1

Therefore the LCM of Fractions 81/97,95/31,18/14,72/33 is 61560
