Know Least Common Multiple of fractions 2792/690, 5646/644 quickly i.e. 7881816/46 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 2792/690, 5646/644 is 7881816/46.
LCM(2792/690, 5646/644) = 7881816/46
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 2792/690,5646/644
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 2792,5646
Least Common Multiple of Numerators i.e. LCM of 2792,5646 is 7881816.
GCF of Denominators means GCF of 690,644 as per the given fractions.
GCF of 690,644 is 46 as it is the largest common factor for these numbers.
Lets's calculate LCM of 2792,5646
2 | 2792, 5646 |
1396, 2823 |
∴ So the LCM of the given numbers is 2 x 1396 x 2823 = 7881816
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 2792,5646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2792,5646) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(2792,5646) x common factors =2 x 1 = 2
LCM(2792,5646) = ( 2792 × 5646 ) / 2
LCM(2792,5646) = 15763632 / 2
LCM(2792,5646) = 7881816
Lets's calculate GCF of 690,644
2 | 690, 644 |
23 | 345, 322 |
15, 14 |
∴ So the GCF of the given numbers is 2 x 23 = 46
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7881816/46
Therefore the LCM of Fractions 2792/690,5646/644 is 7881816/46
