Know Least Common Multiple of fractions 21/689, 793/531, 757/872 quickly i.e. 12606321 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 21/689, 793/531, 757/872 is 12606321.
LCM(21/689, 793/531, 757/872) = 12606321
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 21/689,793/531,757/872
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 21,793,757
Least Common Multiple of Numerators i.e. LCM of 21,793,757 is 12606321.
GCF of Denominators means GCF of 689,531,872 as per the given fractions.
GCF of 689,531,872 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 21,793,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 12606321
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 21,793,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,793,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,793,757) x common factors =1 x 1 = 1
LCM(21,793,757) = ( 21 × 793 × 757 ) / 1
LCM(21,793,757) = 12606321 / 1
LCM(21,793,757) = 12606321
Lets's calculate GCF of 689,531,872
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12606321/1
Therefore the LCM of Fractions 21/689,793/531,757/872 is 12606321
