Least Common Multiple of 99/21,45/12,14/36,91/150

Given numbers are 99/21,45/12,14/36,91/150

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 99,45,14,91

Least Common Multiple of Numerators i.e. LCM of 99,45,14,91 is 90090.

GCF of Denominators means GCF of 21,12,36,150 as per the given fractions.

GCF of 21,12,36,150 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 99,45,14,91

LCM of Fractions 99/21,45/12,14/36,91/150 is 30030

3 99, 45, 14, 91
3 33, 15, 14, 91
7 11, 5, 14, 91
11, 5, 2, 13

∴ So the LCM of the given numbers is 3 x 3 x 7 x 11 x 5 x 2 x 13 = 90090

Least Common Multiple of 99,45,14,91 with GCF Formula

Least Common Multiple of 99,45,14,91 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 99,45,14,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(99,45,14,91) = 1

common factors(in case of two or more numbers have common factors) = 63

GCF(99,45,14,91) x common factors =1 x 63 = 63

LCM(99,45,14,91) = ( 99 × 45 × 14 × 91 ) / 63

LCM(99,45,14,91) = 5675670 / 63

LCM(99,45,14,91) = 90090


Lets's calculate GCF of 21,12,36,150

3 21, 12, 36, 150
7, 4, 12, 50

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 90090/3

Therefore the LCM of Fractions 99/21,45/12,14/36,91/150 is 30030
