Know Least Common Multiple of fractions 643/471, 701/931 quickly i.e. 450743 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 643/471, 701/931 is 450743.
LCM(643/471, 701/931) = 450743
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 643/471,701/931
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 643,701
Least Common Multiple of Numerators i.e. LCM of 643,701 is 450743.
GCF of Denominators means GCF of 471,931 as per the given fractions.
GCF of 471,931 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 643,701
Given numbers has no common factors except 1. So, there LCM is their product i.e 450743
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 643,701 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,701) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,701) x common factors =1 x 1 = 1
LCM(643,701) = ( 643 × 701 ) / 1
LCM(643,701) = 450743 / 1
LCM(643,701) = 450743
Lets's calculate GCF of 471,931
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 450743/1
Therefore the LCM of Fractions 643/471,701/931 is 450743
