:1,2,4,8,89,178,356,712
Greatest Common Factor
We found the factors 661,712 . The biggest common factor number is the GCF number.
So the greatest common factor 661,712 is 1.
Lets's calculate LCM of 746,321
Given numbers has no common factors except 1. So, there LCM is their product i.e 239466
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/239466
Therefore, the GCF of Fractions 661/746,712/321 is 1/239466
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 746,321 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(746,321) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(746,321) x common factors =1 x 1 = 1
LCM(746,321) = ( 746 × 321 ) / 1
LCM(746,321) = 239466 / 1
LCM(746,321) = 239466
