Greatest Common Factor
We found the factors 340,428 . The biggest common factor number is the GCF number.
So the greatest common factor 340,428 is 4.
Lets's calculate LCM of 609,179
Given numbers has no common factors except 1. So, there LCM is their product i.e 109011
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/109011
Therefore, the GCF of Fractions 340/609,428/179 is 4/109011
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 609,179 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(609,179) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(609,179) x common factors =1 x 1 = 1
LCM(609,179) = ( 609 × 179 ) / 1
LCM(609,179) = 109011 / 1
LCM(609,179) = 109011
