Least Common Multiple of 664/18,821/63,164/90

Given numbers are 664/18,821/63,164/90

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 664,821,164

Least Common Multiple of Numerators i.e. LCM of 664,821,164 is 22350904.

GCF of Denominators means GCF of 18,63,90 as per the given fractions.

GCF of 18,63,90 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 664,821,164

LCM of Fractions 664/18,821/63,164/90 is 22350904/9

2 664, 821, 164
2 332, 821, 82
166, 821, 41

∴ So the LCM of the given numbers is 2 x 2 x 166 x 821 x 41 = 22350904

Least Common Multiple of 664,821,164 with GCF Formula

Least Common Multiple of 664,821,164 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 664,821,164 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(664,821,164) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(664,821,164) x common factors =1 x 4 = 4

LCM(664,821,164) = ( 664 × 821 × 164 ) / 4

LCM(664,821,164) = 89403616 / 4

LCM(664,821,164) = 22350904


Lets's calculate GCF of 18,63,90

3 18, 63, 90
3 6, 21, 30
2, 7, 10

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 22350904/9

Therefore the LCM of Fractions 664/18,821/63,164/90 is 22350904/9
