Know Least Common Multiple of fractions 791/381, 9711/520 quickly i.e. 7681401 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 791/381, 9711/520 is 7681401.
LCM(791/381, 9711/520) = 7681401
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 791/381,9711/520
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 791,9711
Least Common Multiple of Numerators i.e. LCM of 791,9711 is 7681401.
GCF of Denominators means GCF of 381,520 as per the given fractions.
GCF of 381,520 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 791,9711
Given numbers has no common factors except 1. So, there LCM is their product i.e 7681401
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 791,9711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(791,9711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(791,9711) x common factors =1 x 1 = 1
LCM(791,9711) = ( 791 × 9711 ) / 1
LCM(791,9711) = 7681401 / 1
LCM(791,9711) = 7681401
Lets's calculate GCF of 381,520
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7681401/1
Therefore the LCM of Fractions 791/381,9711/520 is 7681401
