:1,2,3,6,23,46,69,138
Greatest Common Factor
We found the factors 19,703,138 . The biggest common factor number is the GCF number.
So the greatest common factor 19,703,138 is 1.
Lets's calculate LCM of 68,83,783
Given numbers has no common factors except 1. So, there LCM is their product i.e 4419252
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4419252
Therefore, the GCF of Fractions 19/68,703/83,138/783 is 1/4419252
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 68,83,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,83,783) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,83,783) x common factors =1 x 1 = 1
LCM(68,83,783) = ( 68 × 83 × 783 ) / 1
LCM(68,83,783) = 4419252 / 1
LCM(68,83,783) = 4419252
