Know Least Common Multiple of fractions 8084/72, 4840/142 quickly i.e. 4890820 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 8084/72, 4840/142 is 4890820.
LCM(8084/72, 4840/142) = 4890820
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 8084/72,4840/142
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 8084,4840
Least Common Multiple of Numerators i.e. LCM of 8084,4840 is 9781640.
GCF of Denominators means GCF of 72,142 as per the given fractions.
GCF of 72,142 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 8084,4840
2 | 8084, 4840 |
2 | 4042, 2420 |
2021, 1210 |
∴ So the LCM of the given numbers is 2 x 2 x 2021 x 1210 = 9781640
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 8084,4840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(8084,4840) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(8084,4840) x common factors =4 x 1 = 4
LCM(8084,4840) = ( 8084 × 4840 ) / 4
LCM(8084,4840) = 39126560 / 4
LCM(8084,4840) = 9781640
Lets's calculate GCF of 72,142
2 | 72, 142 |
36, 71 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9781640/2
Therefore the LCM of Fractions 8084/72,4840/142 is 4890820
