1,2,3,6,479,958,1437,2874
Greatest Common Factor
We found the factors 75,2874 . The biggest common factor number is the GCF number.
So the greatest common factor 75,2874 is 3.
Lets's calculate LCM of 457,8120
Given numbers has no common factors except 1. So, there LCM is their product i.e 3710840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/3710840
Therefore, the GCF of Fractions 75/457,2874/8120 is 3/3710840
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 457,8120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,8120) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,8120) x common factors =1 x 1 = 1
LCM(457,8120) = ( 457 × 8120 ) / 1
LCM(457,8120) = 3710840 / 1
LCM(457,8120) = 3710840
