Least Common Multiple of 61/15,35/49,42/67,75/89

Given numbers are 61/15,35/49,42/67,75/89

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 61,35,42,75

Least Common Multiple of Numerators i.e. LCM of 61,35,42,75 is 64050.

GCF of Denominators means GCF of 15,49,67,89 as per the given fractions.

GCF of 15,49,67,89 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 61,35,42,75

LCM of Fractions 61/15,35/49,42/67,75/89 is 64050

3 61, 35, 42, 75
5 61, 35, 14, 25
7 61, 7, 14, 5
61, 1, 2, 5

∴ So the LCM of the given numbers is 3 x 5 x 7 x 61 x 1 x 2 x 5 = 64050

Least Common Multiple of 61,35,42,75 with GCF Formula

Least Common Multiple of 61,35,42,75 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 61,35,42,75 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,35,42,75) = 1

common factors(in case of two or more numbers have common factors) = 105

GCF(61,35,42,75) x common factors =1 x 105 = 105

LCM(61,35,42,75) = ( 61 × 35 × 42 × 75 ) / 105

LCM(61,35,42,75) = 6725250 / 105

LCM(61,35,42,75) = 64050


Lets's calculate GCF of 15,49,67,89

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 64050/1

Therefore the LCM of Fractions 61/15,35/49,42/67,75/89 is 64050
