Greatest Common Factor
We found the factors 1780,9982 . The biggest common factor number is the GCF number.
So the greatest common factor 1780,9982 is 2.
Lets's calculate LCM of 23,105
Given numbers has no common factors except 1. So, there LCM is their product i.e 2415
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2415
Therefore, the GCF of Fractions 1780/23,9982/105 is 2/2415
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 23,105 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,105) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,105) x common factors =1 x 1 = 1
LCM(23,105) = ( 23 × 105 ) / 1
LCM(23,105) = 2415 / 1
LCM(23,105) = 2415
