Greatest Common Factor
We found the factors 860,688 . The biggest common factor number is the GCF number.
So the greatest common factor 860,688 is 172.
Lets's calculate LCM of 40,7601
Given numbers has no common factors except 1. So, there LCM is their product i.e 304040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 172/304040
Therefore, the GCF of Fractions 860/40,688/7601 is 172/304040
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 40,7601 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,7601) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(40,7601) x common factors =1 x 1 = 1
LCM(40,7601) = ( 40 × 7601 ) / 1
LCM(40,7601) = 304040 / 1
LCM(40,7601) = 304040
