Greatest Common Factor
We found the factors 85,260,219 . The biggest common factor number is the GCF number.
So the greatest common factor 85,260,219 is 1.
Lets's calculate LCM of 331,151,490
Given numbers has no common factors except 1. So, there LCM is their product i.e 24490690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24490690
Therefore, the GCF of Fractions 85/331,260/151,219/490 is 1/24490690
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 331,151,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(331,151,490) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(331,151,490) x common factors =1 x 1 = 1
LCM(331,151,490) = ( 331 × 151 × 490 ) / 1
LCM(331,151,490) = 24490690 / 1
LCM(331,151,490) = 24490690
