So the greatest common factor 279,855 is 9.
Lets's calculate LCM of 207,727
Given numbers has no common factors except 1. So, there LCM is their product i.e 150489
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/150489
Therefore, the GCF of Fractions 279/207,855/727 is 9/150489
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 207,727 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,727) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(207,727) x common factors =1 x 1 = 1
LCM(207,727) = ( 207 × 727 ) / 1
LCM(207,727) = 150489 / 1
LCM(207,727) = 150489
