Greatest Common Factor
We found the factors 43,85,630 . The biggest common factor number is the GCF number.
So the greatest common factor 43,85,630 is 1.
Lets's calculate LCM of 71,40,581
Given numbers has no common factors except 1. So, there LCM is their product i.e 1650040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1650040
Therefore, the GCF of Fractions 43/71,85/40,630/581 is 1/1650040
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 71,40,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,40,581) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,40,581) x common factors =1 x 1 = 1
LCM(71,40,581) = ( 71 × 40 × 581 ) / 1
LCM(71,40,581) = 1650040 / 1
LCM(71,40,581) = 1650040
