Greatest Common Factor
We found the factors 686,210,616 . The biggest common factor number is the GCF number.
So the greatest common factor 686,210,616 is 14.
Lets's calculate LCM of 87,91,80
Given numbers has no common factors except 1. So, there LCM is their product i.e 633360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/633360
Therefore, the GCF of Fractions 686/87,210/91,616/80 is 14/633360
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 87,91,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,91,80) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(87,91,80) x common factors =1 x 1 = 1
LCM(87,91,80) = ( 87 × 91 × 80 ) / 1
LCM(87,91,80) = 633360 / 1
LCM(87,91,80) = 633360
