Least Common Multiple of 990/448,1161/172

Given numbers are 990/448,1161/172

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 990,1161

Least Common Multiple of Numerators i.e. LCM of 990,1161 is 127710.

GCF of Denominators means GCF of 448,172 as per the given fractions.

GCF of 448,172 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 990,1161

LCM of Fractions 990/448,1161/172 is 127710/4

3 990, 1161
3 330, 387
110, 129

∴ So the LCM of the given numbers is 3 x 3 x 110 x 129 = 127710

Least Common Multiple of 990,1161 with GCF Formula

Least Common Multiple of 990,1161 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 990,1161 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(990,1161) = 9

common factors(in case of two or more numbers have common factors) = 1

GCF(990,1161) x common factors =9 x 1 = 9

LCM(990,1161) = ( 990 × 1161 ) / 9

LCM(990,1161) = 1149390 / 9

LCM(990,1161) = 127710


Lets's calculate GCF of 448,172

2 448, 172
2 224, 86
112, 43

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 127710/4

Therefore the LCM of Fractions 990/448,1161/172 is 127710/4
