:1,2,3,6,131,262,393,786
Greatest Common Factor
We found the factors 27,63,786 . The biggest common factor number is the GCF number.
So the greatest common factor 27,63,786 is 3.
Lets's calculate LCM of 621,958,109
Given numbers has no common factors except 1. So, there LCM is their product i.e 64846062
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/64846062
Therefore, the GCF of Fractions 27/621,63/958,786/109 is 3/64846062
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 621,958,109 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(621,958,109) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(621,958,109) x common factors =1 x 1 = 1
LCM(621,958,109) = ( 621 × 958 × 109 ) / 1
LCM(621,958,109) = 64846062 / 1
LCM(621,958,109) = 64846062
