Lets's calculate LCM of 643,4207
Given numbers has no common factors except 1. So, there LCM is their product i.e 2705101
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/2705101
Therefore, the GCF of Fractions 55/643,2277/4207 is 11/2705101
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 643,4207 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,4207) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,4207) x common factors =1 x 1 = 1
LCM(643,4207) = ( 643 × 4207 ) / 1
LCM(643,4207) = 2705101 / 1
LCM(643,4207) = 2705101
