Know Least Common Multiple of fractions 138/90, 792/664 quickly i.e. 9108 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 138/90, 792/664 is 9108.
LCM(138/90, 792/664) = 9108
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 138/90,792/664
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 138,792
Least Common Multiple of Numerators i.e. LCM of 138,792 is 18216.
GCF of Denominators means GCF of 90,664 as per the given fractions.
GCF of 90,664 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 138,792
2 | 138, 792 |
3 | 69, 396 |
23, 132 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 132 = 18216
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 138,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,792) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(138,792) x common factors =6 x 1 = 6
LCM(138,792) = ( 138 × 792 ) / 6
LCM(138,792) = 109296 / 6
LCM(138,792) = 18216
Lets's calculate GCF of 90,664
2 | 90, 664 |
45, 332 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 18216/2
Therefore the LCM of Fractions 138/90,792/664 is 9108
