Know Least Common Multiple of fractions 1320/36, 3891/154 quickly i.e. 856020 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1320/36, 3891/154 is 856020.
LCM(1320/36, 3891/154) = 856020
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1320/36,3891/154
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 1320,3891
Least Common Multiple of Numerators i.e. LCM of 1320,3891 is 1712040.
GCF of Denominators means GCF of 36,154 as per the given fractions.
GCF of 36,154 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1320,3891
3 | 1320, 3891 |
440, 1297 |
∴ So the LCM of the given numbers is 3 x 440 x 1297 = 1712040
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 1320,3891 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1320,3891) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(1320,3891) x common factors =3 x 1 = 3
LCM(1320,3891) = ( 1320 × 3891 ) / 3
LCM(1320,3891) = 5136120 / 3
LCM(1320,3891) = 1712040
Lets's calculate GCF of 36,154
2 | 36, 154 |
18, 77 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1712040/2
Therefore the LCM of Fractions 1320/36,3891/154 is 856020
