:1,3,17,41,51,123,697,2091
Greatest Common Factor
We found the factors 2821,2091 . The biggest common factor number is the GCF number.
So the greatest common factor 2821,2091 is 1.
Lets's calculate LCM of 645,869
Given numbers has no common factors except 1. So, there LCM is their product i.e 560505
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/560505
Therefore, the GCF of Fractions 2821/645,2091/869 is 1/560505
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 645,869 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,869) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,869) x common factors =1 x 1 = 1
LCM(645,869) = ( 645 × 869 ) / 1
LCM(645,869) = 560505 / 1
LCM(645,869) = 560505
