LCM(90/805, 21/791) = 90

LCM of 90/805, 21/791

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 90/805,21/791

Given numbers are 90/805,21/791

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 90,21

Least Common Multiple of Numerators i.e. LCM of 90,21 is 630.

GCF of Denominators means GCF of 805,791 as per the given fractions.

GCF of 805,791 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 90,21

LCM of Fractions 90/805,21/791 is 90

3 90, 21
30, 7

∴ So the LCM of the given numbers is 3 x 30 x 7 = 630

Least Common Multiple of 90,21 with GCF Formula

Least Common Multiple of 90,21 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 90,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,21) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(90,21) x common factors =3 x 1 = 3

LCM(90,21) = ( 90 × 21 ) / 3

LCM(90,21) = 1890 / 3

LCM(90,21) = 630


Lets's calculate GCF of 805,791

7 805, 791
115, 113

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 630/7

Therefore the LCM of Fractions 90/805,21/791 is 90
