1,2,3,6,9,13,18,26,39,78,117,234
Greatest Common Factor
We found the factors 15,651,234 . The biggest common factor number is the GCF number.
So the greatest common factor 15,651,234 is 3.
Lets's calculate LCM of 21,71,493
Given numbers has no common factors except 1. So, there LCM is their product i.e 735063
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/735063
Therefore, the GCF of Fractions 15/21,651/71,234/493 is 3/735063
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 21,71,493 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,71,493) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,71,493) x common factors =1 x 1 = 1
LCM(21,71,493) = ( 21 × 71 × 493 ) / 1
LCM(21,71,493) = 735063 / 1
LCM(21,71,493) = 735063
Here are some samples of GCF of Fractions calculations.
