Know Least Common Multiple of fractions 142/91, 8053/420 quickly i.e. 1143526/7 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 142/91, 8053/420 is 1143526/7.
LCM(142/91, 8053/420) = 1143526/7
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 142/91,8053/420
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 142,8053
Least Common Multiple of Numerators i.e. LCM of 142,8053 is 1143526.
GCF of Denominators means GCF of 91,420 as per the given fractions.
GCF of 91,420 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 142,8053
Given numbers has no common factors except 1. So, there LCM is their product i.e 1143526
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 142,8053 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(142,8053) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(142,8053) x common factors =1 x 1 = 1
LCM(142,8053) = ( 142 × 8053 ) / 1
LCM(142,8053) = 1143526 / 1
LCM(142,8053) = 1143526
Lets's calculate GCF of 91,420
7 | 91, 420 |
13, 60 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1143526/7
Therefore the LCM of Fractions 142/91,8053/420 is 1143526/7
