Greatest Common Factor
We found the factors 19,71,689 . The biggest common factor number is the GCF number.
So the greatest common factor 19,71,689 is 1.
Lets's calculate LCM of 139,357,479
Given numbers has no common factors except 1. So, there LCM is their product i.e 23769417
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23769417
Therefore, the GCF of Fractions 19/139,71/357,689/479 is 1/23769417
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 139,357,479 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(139,357,479) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(139,357,479) x common factors =1 x 1 = 1
LCM(139,357,479) = ( 139 × 357 × 479 ) / 1
LCM(139,357,479) = 23769417 / 1
LCM(139,357,479) = 23769417
