Greatest Common Factor
We found the factors 343,698 . The biggest common factor number is the GCF number.
So the greatest common factor 343,698 is 1.
Lets's calculate LCM of 620,647
Given numbers has no common factors except 1. So, there LCM is their product i.e 401140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/401140
Therefore, the GCF of Fractions 343/620,698/647 is 1/401140
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 620,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,647) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(620,647) x common factors =1 x 1 = 1
LCM(620,647) = ( 620 × 647 ) / 1
LCM(620,647) = 401140 / 1
LCM(620,647) = 401140
