Greatest Common Factor
We found the factors 78,484,903 . The biggest common factor number is the GCF number.
So the greatest common factor 78,484,903 is 1.
Lets's calculate LCM of 91,53,153
Given numbers has no common factors except 1. So, there LCM is their product i.e 737919
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/737919
Therefore, the GCF of Fractions 78/91,484/53,903/153 is 1/737919
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 91,53,153 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,53,153) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,53,153) x common factors =1 x 1 = 1
LCM(91,53,153) = ( 91 × 53 × 153 ) / 1
LCM(91,53,153) = 737919 / 1
LCM(91,53,153) = 737919
