Greatest Common Factor
We found the factors 985,469,628 . The biggest common factor number is the GCF number.
So the greatest common factor 985,469,628 is 1.
Lets's calculate LCM of 89,40,19
Given numbers has no common factors except 1. So, there LCM is their product i.e 67640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67640
Therefore, the GCF of Fractions 985/89,469/40,628/19 is 1/67640
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 89,40,19 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,40,19) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,40,19) x common factors =1 x 1 = 1
LCM(89,40,19) = ( 89 × 40 × 19 ) / 1
LCM(89,40,19) = 67640 / 1
LCM(89,40,19) = 67640
