Know Least Common Multiple of fractions 648/980, 1672/1571 quickly i.e. 135432 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 648/980, 1672/1571 is 135432.
LCM(648/980, 1672/1571) = 135432
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 648/980,1672/1571
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 648,1672
Least Common Multiple of Numerators i.e. LCM of 648,1672 is 135432.
GCF of Denominators means GCF of 980,1571 as per the given fractions.
GCF of 980,1571 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 648,1672
2 | 648, 1672 |
2 | 324, 836 |
2 | 162, 418 |
81, 209 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 81 x 209 = 135432
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 648,1672 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(648,1672) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(648,1672) x common factors =8 x 1 = 8
LCM(648,1672) = ( 648 × 1672 ) / 8
LCM(648,1672) = 1083456 / 8
LCM(648,1672) = 135432
Lets's calculate GCF of 980,1571
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 135432/1
Therefore the LCM of Fractions 648/980,1672/1571 is 135432
