:1,2,3,6,9,13,18,26,27,39,54,78,117,234,351,702
Greatest Common Factor
We found the factors 990,702 . The biggest common factor number is the GCF number.
So the greatest common factor 990,702 is 18.
Lets's calculate LCM of 629,120
Given numbers has no common factors except 1. So, there LCM is their product i.e 75480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/75480
Therefore, the GCF of Fractions 990/629,702/120 is 18/75480
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 629,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(629,120) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(629,120) x common factors =1 x 1 = 1
LCM(629,120) = ( 629 × 120 ) / 1
LCM(629,120) = 75480 / 1
LCM(629,120) = 75480
