Greatest Common Factor
We found the factors 153,623 . The biggest common factor number is the GCF number.
So the greatest common factor 153,623 is 1.
Lets's calculate LCM of 813,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 98373
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/98373
Therefore, the GCF of Fractions 153/813,623/121 is 1/98373
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 813,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(813,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(813,121) x common factors =1 x 1 = 1
LCM(813,121) = ( 813 × 121 ) / 1
LCM(813,121) = 98373 / 1
LCM(813,121) = 98373
