Least Common Multiple of 87/70,84/77,79/14,89/987

Given numbers are 87/70,84/77,79/14,89/987

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 87,84,79,89

Least Common Multiple of Numerators i.e. LCM of 87,84,79,89 is 17127516.

GCF of Denominators means GCF of 70,77,14,987 as per the given fractions.

GCF of 70,77,14,987 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 87,84,79,89

LCM of Fractions 87/70,84/77,79/14,89/987 is 2446788

3 87, 84, 79, 89
29, 28, 79, 89

∴ So the LCM of the given numbers is 3 x 29 x 28 x 79 x 89 = 17127516

Least Common Multiple of 87,84,79,89 with GCF Formula

Least Common Multiple of 87,84,79,89 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 87,84,79,89 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,84,79,89) = 1

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

GCF(87,84,79,89) x common factors =1 x 3 = 3

LCM(87,84,79,89) = ( 87 × 84 × 79 × 89 ) / 3

LCM(87,84,79,89) = 51382548 / 3

LCM(87,84,79,89) = 17127516


Lets's calculate GCF of 70,77,14,987

7 70, 77, 14, 987
10, 11, 2, 141

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 17127516/7

Therefore the LCM of Fractions 87/70,84/77,79/14,89/987 is 2446788
