Least Common Multiple of 42/60,168/90,620/470

Given numbers are 42/60,168/90,620/470

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 42,168,620

Least Common Multiple of Numerators i.e. LCM of 42,168,620 is 26040.

GCF of Denominators means GCF of 60,90,470 as per the given fractions.

GCF of 60,90,470 is 10 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,168,620

LCM of Fractions 42/60,168/90,620/470 is 2604

2 42, 168, 620
2 21, 84, 310
3 21, 42, 155
7 7, 14, 155
1, 2, 155

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 1 x 2 x 155 = 26040

Least Common Multiple of 42,168,620 with GCF Formula

Least Common Multiple of 42,168,620 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 42,168,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,168,620) = 2

common factors(in case of two or more numbers have common factors) = 84

GCF(42,168,620) x common factors =2 x 84 = 168

LCM(42,168,620) = ( 42 × 168 × 620 ) / 168

LCM(42,168,620) = 4374720 / 168

LCM(42,168,620) = 26040


Lets's calculate GCF of 60,90,470

2 60, 90, 470
5 30, 45, 235
6, 9, 47

∴ So the GCF of the given numbers is 2 x 5 = 10

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 26040/10

Therefore the LCM of Fractions 42/60,168/90,620/470 is 2604
