:1,2,3,6,137,274,411,822
Greatest Common Factor
We found the factors 810,822 . The biggest common factor number is the GCF number.
So the greatest common factor 810,822 is 6.
Lets's calculate LCM of 985,387
Given numbers has no common factors except 1. So, there LCM is their product i.e 381195
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/381195
Therefore, the GCF of Fractions 810/985,822/387 is 6/381195
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 985,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,387) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(985,387) x common factors =1 x 1 = 1
LCM(985,387) = ( 985 × 387 ) / 1
LCM(985,387) = 381195 / 1
LCM(985,387) = 381195
