Greatest Common Factor
We found the factors 358,655 . The biggest common factor number is the GCF number.
So the greatest common factor 358,655 is 1.
Lets's calculate LCM of 839,728
Given numbers has no common factors except 1. So, there LCM is their product i.e 610792
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/610792
Therefore, the GCF of Fractions 358/839,655/728 is 1/610792
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 839,728 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(839,728) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(839,728) x common factors =1 x 1 = 1
LCM(839,728) = ( 839 × 728 ) / 1
LCM(839,728) = 610792 / 1
LCM(839,728) = 610792
