LCM of:

Least Common Multiple of 161/72,421/53,805/63

Given numbers are 161/72,421/53,805/63

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 161,421,805

Least Common Multiple of Numerators i.e. LCM of 161,421,805 is 338905.

GCF of Denominators means GCF of 72,53,63 as per the given fractions.

GCF of 72,53,63 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 161,421,805

LCM of Fractions 161/72,421/53,805/63 is 338905

7 161, 421, 805
23 23, 421, 115
1, 421, 5

∴ So the LCM of the given numbers is 7 x 23 x 1 x 421 x 5 = 338905

Least Common Multiple of 161,421,805 with GCF Formula

Least Common Multiple of 161,421,805 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 161,421,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(161,421,805) = 1

common factors(in case of two or more numbers have common factors) = 161

GCF(161,421,805) x common factors =1 x 161 = 161

LCM(161,421,805) = ( 161 × 421 × 805 ) / 161

LCM(161,421,805) = 54563705 / 161

LCM(161,421,805) = 338905


Lets's calculate GCF of 72,53,63

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 338905/1

Therefore the LCM of Fractions 161/72,421/53,805/63 is 338905
