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 643,987,807

Least Common Multiple of Numerators i.e. LCM of 643,987,807 is 170718429.

GCF of Denominators means GCF of 24,72,896 as per the given fractions.

GCF of 24,72,896 is 8 as it is the largest common factor for these numbers.

Lets's calculate LCM of 643,987,807

LCM of Fractions 643/24,987/72,807/896 is 170718429/8

3 643, 987, 807
643, 329, 269

∴ So the LCM of the given numbers is 3 x 643 x 329 x 269 = 170718429

Least Common Multiple of 643,987,807 with GCF Formula

Least Common Multiple of 643,987,807 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 643,987,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,987,807) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(643,987,807) x common factors =1 x 3 = 3

LCM(643,987,807) = ( 643 × 987 × 807 ) / 3

LCM(643,987,807) = 512155287 / 3

LCM(643,987,807) = 170718429


Lets's calculate GCF of 24,72,896

2 24, 72, 896
2 12, 36, 448
2 6, 18, 224
3, 9, 112

∴ So the GCF of the given numbers is 2 x 2 x 2 = 8

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 170718429/8

Therefore the LCM of Fractions 643/24,987/72,807/896 is 170718429/8
