Least Common Multiple of 90/86,78/20,974/928

Given numbers are 90/86,78/20,974/928

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 90,78,974

Least Common Multiple of Numerators i.e. LCM of 90,78,974 is 569790.

GCF of Denominators means GCF of 86,20,928 as per the given fractions.

GCF of 86,20,928 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,78,974

LCM of Fractions 90/86,78/20,974/928 is 284895

2 90, 78, 974
3 45, 39, 487
15, 13, 487

∴ So the LCM of the given numbers is 2 x 3 x 15 x 13 x 487 = 569790

Least Common Multiple of 90,78,974 with GCF Formula

Least Common Multiple of 90,78,974 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 90,78,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,78,974) = 2

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

GCF(90,78,974) x common factors =2 x 6 = 12

LCM(90,78,974) = ( 90 × 78 × 974 ) / 12

LCM(90,78,974) = 6837480 / 12

LCM(90,78,974) = 569790


Lets's calculate GCF of 86,20,928

2 86, 20, 928
43, 10, 464

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 569790/2

Therefore the LCM of Fractions 90/86,78/20,974/928 is 284895
