Lets's calculate LCM of 637,905
Given numbers has no common factors except 1. So, there LCM is their product i.e 576485
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/576485
Therefore, the GCF of Fractions 279/637,846/905 is 9/576485
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 637,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(637,905) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(637,905) x common factors =1 x 1 = 1
LCM(637,905) = ( 637 × 905 ) / 1
LCM(637,905) = 576485 / 1
LCM(637,905) = 576485
