Greatest Common Factor
We found the factors 47,305,665 . The biggest common factor number is the GCF number.
So the greatest common factor 47,305,665 is 1.
Lets's calculate LCM of 79,75,878
Given numbers has no common factors except 1. So, there LCM is their product i.e 5202150
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5202150
Therefore, the GCF of Fractions 47/79,305/75,665/878 is 1/5202150
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 79,75,878 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,75,878) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,75,878) x common factors =1 x 1 = 1
LCM(79,75,878) = ( 79 × 75 × 878 ) / 1
LCM(79,75,878) = 5202150 / 1
LCM(79,75,878) = 5202150
