Least Common Multiple of 45/44,72/20,620/414

Given numbers are 45/44,72/20,620/414

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 45,72,620

Least Common Multiple of Numerators i.e. LCM of 45,72,620 is 11160.

GCF of Denominators means GCF of 44,20,414 as per the given fractions.

GCF of 44,20,414 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 45,72,620

LCM of Fractions 45/44,72/20,620/414 is 5580

2 45, 72, 620
2 45, 36, 310
3 45, 18, 155
3 15, 6, 155
5 5, 2, 155
1, 2, 31

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 1 x 2 x 31 = 11160

Least Common Multiple of 45,72,620 with GCF Formula

Least Common Multiple of 45,72,620 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 45,72,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,72,620) = 1

common factors(in case of two or more numbers have common factors) = 180

GCF(45,72,620) x common factors =1 x 180 = 180

LCM(45,72,620) = ( 45 × 72 × 620 ) / 180

LCM(45,72,620) = 2008800 / 180

LCM(45,72,620) = 11160


Lets's calculate GCF of 44,20,414

2 44, 20, 414
22, 10, 207

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11160/2

Therefore the LCM of Fractions 45/44,72/20,620/414 is 5580
