:1,271
Greatest Common Factor
We found the factors 693,271 . The biggest common factor number is the GCF number.
So the greatest common factor 693,271 is 1.
Lets's calculate LCM of 309,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 197142
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/197142
Therefore, the GCF of Fractions 693/309,271/638 is 1/197142
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 309,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(309,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(309,638) x common factors =1 x 1 = 1
LCM(309,638) = ( 309 × 638 ) / 1
LCM(309,638) = 197142 / 1
LCM(309,638) = 197142
