LCM of:

Least Common Multiple of 684/21,105/63,362/98

Given numbers are 684/21,105/63,362/98

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 684,105,362

Least Common Multiple of Numerators i.e. LCM of 684,105,362 is 4333140.

GCF of Denominators means GCF of 21,63,98 as per the given fractions.

GCF of 21,63,98 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 684,105,362

LCM of Fractions 684/21,105/63,362/98 is 619020

2 684, 105, 362
3 342, 105, 181
114, 35, 181

∴ So the LCM of the given numbers is 2 x 3 x 114 x 35 x 181 = 4333140

Least Common Multiple of 684,105,362 with GCF Formula

Least Common Multiple of 684,105,362 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 684,105,362 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(684,105,362) = 1

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

GCF(684,105,362) x common factors =1 x 6 = 6

LCM(684,105,362) = ( 684 × 105 × 362 ) / 6

LCM(684,105,362) = 25998840 / 6

LCM(684,105,362) = 4333140


Lets's calculate GCF of 21,63,98

7 21, 63, 98
3, 9, 14

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4333140/7

Therefore the LCM of Fractions 684/21,105/63,362/98 is 619020
