Greatest Common Factor
We found the factors 142,287,194 . The biggest common factor number is the GCF number.
So the greatest common factor 142,287,194 is 1.
Lets's calculate LCM of 20,21,53
Given numbers has no common factors except 1. So, there LCM is their product i.e 22260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22260
Therefore, the GCF of Fractions 142/20,287/21,194/53 is 1/22260
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 20,21,53 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,21,53) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(20,21,53) x common factors =1 x 1 = 1
LCM(20,21,53) = ( 20 × 21 × 53 ) / 1
LCM(20,21,53) = 22260 / 1
LCM(20,21,53) = 22260
