Know Least Common Multiple of fractions 609/521, 138/639 quickly i.e. 28014 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 609/521, 138/639 is 28014.
LCM(609/521, 138/639) = 28014
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 609/521,138/639
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 609,138
Least Common Multiple of Numerators i.e. LCM of 609,138 is 28014.
GCF of Denominators means GCF of 521,639 as per the given fractions.
GCF of 521,639 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 609,138
3 | 609, 138 |
203, 46 |
∴ So the LCM of the given numbers is 3 x 203 x 46 = 28014
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 609,138 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(609,138) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(609,138) x common factors =3 x 1 = 3
LCM(609,138) = ( 609 × 138 ) / 3
LCM(609,138) = 84042 / 3
LCM(609,138) = 28014
Lets's calculate GCF of 521,639
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28014/1
Therefore the LCM of Fractions 609/521,138/639 is 28014
