Know Least Common Multiple of fractions 71/19, 25/169, 799/742 quickly i.e. 1418225 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 71/19, 25/169, 799/742 is 1418225.
LCM(71/19, 25/169, 799/742) = 1418225
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 71/19,25/169,799/742
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 71,25,799
Least Common Multiple of Numerators i.e. LCM of 71,25,799 is 1418225.
GCF of Denominators means GCF of 19,169,742 as per the given fractions.
GCF of 19,169,742 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 71,25,799
Given numbers has no common factors except 1. So, there LCM is their product i.e 1418225
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 71,25,799 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,25,799) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,25,799) x common factors =1 x 1 = 1
LCM(71,25,799) = ( 71 × 25 × 799 ) / 1
LCM(71,25,799) = 1418225 / 1
LCM(71,25,799) = 1418225
Lets's calculate GCF of 19,169,742
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1418225/1
Therefore the LCM of Fractions 71/19,25/169,799/742 is 1418225
