Least Common Multiple of 687/80,980/70,738/105

Given numbers are 687/80,980/70,738/105

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 687,980,738

Least Common Multiple of Numerators i.e. LCM of 687,980,738 is 82810980.

GCF of Denominators means GCF of 80,70,105 as per the given fractions.

GCF of 80,70,105 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 687,980,738

LCM of Fractions 687/80,980/70,738/105 is 16562196

2 687, 980, 738
3 687, 490, 369
229, 490, 123

∴ So the LCM of the given numbers is 2 x 3 x 229 x 490 x 123 = 82810980

Least Common Multiple of 687,980,738 with GCF Formula

Least Common Multiple of 687,980,738 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 687,980,738 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(687,980,738) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(687,980,738) x common factors =1 x 6 = 6

LCM(687,980,738) = ( 687 × 980 × 738 ) / 6

LCM(687,980,738) = 496865880 / 6

LCM(687,980,738) = 82810980


Lets's calculate GCF of 80,70,105

5 80, 70, 105
16, 14, 21

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 82810980/5

Therefore the LCM of Fractions 687/80,980/70,738/105 is 16562196
