Greatest Common Factor
We found the factors 423,713 . The biggest common factor number is the GCF number.
So the greatest common factor 423,713 is 1.
Lets's calculate LCM of 768,205
Given numbers has no common factors except 1. So, there LCM is their product i.e 157440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/157440
Therefore, the GCF of Fractions 423/768,713/205 is 1/157440
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 768,205 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,205) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(768,205) x common factors =1 x 1 = 1
LCM(768,205) = ( 768 × 205 ) / 1
LCM(768,205) = 157440 / 1
LCM(768,205) = 157440
