:1,2,3,4,6,8,12,16,17,24,34,48,51,68,102,136,204,272,408,816
Greatest Common Factor
We found the factors 688,816 . The biggest common factor number is the GCF number.
So the greatest common factor 688,816 is 16.
Lets's calculate LCM of 931,464
Given numbers has no common factors except 1. So, there LCM is their product i.e 431984
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/431984
Therefore, the GCF of Fractions 688/931,816/464 is 16/431984
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 931,464 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,464) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(931,464) x common factors =1 x 1 = 1
LCM(931,464) = ( 931 × 464 ) / 1
LCM(931,464) = 431984 / 1
LCM(931,464) = 431984
