Least Common Multiple of 56/78,840/62,974/800

Given numbers are 56/78,840/62,974/800

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 56,840,974

Least Common Multiple of Numerators i.e. LCM of 56,840,974 is 409080.

GCF of Denominators means GCF of 78,62,800 as per the given fractions.

GCF of 78,62,800 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 56,840,974

LCM of Fractions 56/78,840/62,974/800 is 204540

2 56, 840, 974
2 28, 420, 487
2 14, 210, 487
7 7, 105, 487
1, 15, 487

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 1 x 15 x 487 = 409080

Least Common Multiple of 56,840,974 with GCF Formula

Least Common Multiple of 56,840,974 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 56,840,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,840,974) = 2

common factors(in case of two or more numbers have common factors) = 56

GCF(56,840,974) x common factors =2 x 56 = 112

LCM(56,840,974) = ( 56 × 840 × 974 ) / 112

LCM(56,840,974) = 45816960 / 112

LCM(56,840,974) = 409080


Lets's calculate GCF of 78,62,800

2 78, 62, 800
39, 31, 400

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 409080/2

Therefore the LCM of Fractions 56/78,840/62,974/800 is 204540
