:1,2,7,14,31,62,217,434
Greatest Common Factor
We found the factors 743,434 . The biggest common factor number is the GCF number.
So the greatest common factor 743,434 is 1.
Lets's calculate LCM of 778,155
Given numbers has no common factors except 1. So, there LCM is their product i.e 120590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/120590
Therefore, the GCF of Fractions 743/778,434/155 is 1/120590
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 778,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(778,155) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(778,155) x common factors =1 x 1 = 1
LCM(778,155) = ( 778 × 155 ) / 1
LCM(778,155) = 120590 / 1
LCM(778,155) = 120590
