Know Least Common Multiple of fractions 2097/980, 1571/308 quickly i.e. 3294387/28 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 2097/980, 1571/308 is 3294387/28.
LCM(2097/980, 1571/308) = 3294387/28
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 2097/980,1571/308
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 2097,1571
Least Common Multiple of Numerators i.e. LCM of 2097,1571 is 3294387.
GCF of Denominators means GCF of 980,308 as per the given fractions.
GCF of 980,308 is 28 as it is the largest common factor for these numbers.
Lets's calculate LCM of 2097,1571
Given numbers has no common factors except 1. So, there LCM is their product i.e 3294387
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 2097,1571 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2097,1571) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(2097,1571) x common factors =1 x 1 = 1
LCM(2097,1571) = ( 2097 × 1571 ) / 1
LCM(2097,1571) = 3294387 / 1
LCM(2097,1571) = 3294387
Lets's calculate GCF of 980,308
2 | 980, 308 |
2 | 490, 154 |
7 | 245, 77 |
35, 11 |
∴ So the GCF of the given numbers is 2 x 2 x 7 = 28
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3294387/28
Therefore the LCM of Fractions 2097/980,1571/308 is 3294387/28
