Least Common Multiple (LCM) of 399/720, 788/979 is 314412.
LCM(399/720, 788/979) = 314412
LCM of 399/720, 788/979
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 399/720,788/979
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 399,788
Least Common Multiple of Numerators i.e. LCM of 399,788 is 314412.
GCF of Denominators means GCF of 720,979 as per the given fractions.
GCF of 720,979 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 399,788
LCM of Fractions 399/720,788/979 is 314412
Given numbers has no common factors except 1. So, there LCM is their product i.e 314412
Least Common Multiple of 399,788 with GCF Formula
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 399,788 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(399,788) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(399,788) x common factors =1 x 1 = 1
LCM(399,788) = ( 399 × 788 ) / 1
LCM(399,788) = 314412 / 1
LCM(399,788) = 314412
Lets's calculate GCF of 720,979
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 314412/1
Therefore the LCM of Fractions 399/720,788/979 is 314412
