Least Common Multiple of 45/84,246/72,140/490

Given numbers are 45/84,246/72,140/490

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 45,246,140

Least Common Multiple of Numerators i.e. LCM of 45,246,140 is 51660.

GCF of Denominators means GCF of 84,72,490 as per the given fractions.

GCF of 84,72,490 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 45,246,140

LCM of Fractions 45/84,246/72,140/490 is 25830

2 45, 246, 140
3 45, 123, 70
5 15, 41, 70
3, 41, 14

∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 41 x 14 = 51660

Least Common Multiple of 45,246,140 with GCF Formula

Least Common Multiple of 45,246,140 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 45,246,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,246,140) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(45,246,140) x common factors =1 x 30 = 30

LCM(45,246,140) = ( 45 × 246 × 140 ) / 30

LCM(45,246,140) = 1549800 / 30

LCM(45,246,140) = 51660


Lets's calculate GCF of 84,72,490

2 84, 72, 490
42, 36, 245

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 51660/2

Therefore the LCM of Fractions 45/84,246/72,140/490 is 25830
