Know Least Common Multiple of fractions 21/168, 547/231, 254/525 quickly i.e. 138938 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 21/168, 547/231, 254/525 is 138938.
LCM(21/168, 547/231, 254/525) = 138938
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 21/168,547/231,254/525
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 21,547,254
Least Common Multiple of Numerators i.e. LCM of 21,547,254 is 2917698.
GCF of Denominators means GCF of 168,231,525 as per the given fractions.
GCF of 168,231,525 is 21 as it is the largest common factor for these numbers.
Lets's calculate LCM of 21,547,254
Given numbers has no common factors except 1. So, there LCM is their product i.e 2917698
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 21,547,254 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,547,254) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,547,254) x common factors =1 x 1 = 1
LCM(21,547,254) = ( 21 × 547 × 254 ) / 1
LCM(21,547,254) = 2917698 / 1
LCM(21,547,254) = 2917698
Lets's calculate GCF of 168,231,525
3 | 168, 231, 525 |
7 | 56, 77, 175 |
8, 11, 25 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2917698/21
Therefore the LCM of Fractions 21/168,547/231,254/525 is 138938
