:1,3,7,21,101,303,707,2121
Greatest Common Factor
We found the factors 714,2121 . The biggest common factor number is the GCF number.
So the greatest common factor 714,2121 is 21.
Lets's calculate LCM of 843,251
Given numbers has no common factors except 1. So, there LCM is their product i.e 211593
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/211593
Therefore, the GCF of Fractions 714/843,2121/251 is 21/211593
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 843,251 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(843,251) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(843,251) x common factors =1 x 1 = 1
LCM(843,251) = ( 843 × 251 ) / 1
LCM(843,251) = 211593 / 1
LCM(843,251) = 211593
