1,2,3,4,6,12,53,106,159,212,318,636
Greatest Common Factor
We found the factors 969,636 . The biggest common factor number is the GCF number.
So the greatest common factor 969,636 is 3.
Lets's calculate LCM of 921,340
Given numbers has no common factors except 1. So, there LCM is their product i.e 313140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/313140
Therefore, the GCF of Fractions 969/921,636/340 is 3/313140
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 921,340 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,340) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,340) x common factors =1 x 1 = 1
LCM(921,340) = ( 921 × 340 ) / 1
LCM(921,340) = 313140 / 1
LCM(921,340) = 313140
