Least Common Multiple of 54/248,70/172,990/669

Given numbers are 54/248,70/172,990/669

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 54,70,990

Least Common Multiple of Numerators i.e. LCM of 54,70,990 is 20790.

GCF of Denominators means GCF of 248,172,669 as per the given fractions.

GCF of 248,172,669 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 54,70,990

LCM of Fractions 54/248,70/172,990/669 is 20790

2 54, 70, 990
3 27, 35, 495
3 9, 35, 165
5 3, 35, 55
3, 7, 11

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 3 x 7 x 11 = 20790

Least Common Multiple of 54,70,990 with GCF Formula

Least Common Multiple of 54,70,990 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 54,70,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,70,990) = 2

common factors(in case of two or more numbers have common factors) = 90

GCF(54,70,990) x common factors =2 x 90 = 180

LCM(54,70,990) = ( 54 × 70 × 990 ) / 180

LCM(54,70,990) = 3742200 / 180

LCM(54,70,990) = 20790


Lets's calculate GCF of 248,172,669

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 20790/1

Therefore the LCM of Fractions 54/248,70/172,990/669 is 20790
