Lets's calculate LCM of 643,869
Given numbers has no common factors except 1. So, there LCM is their product i.e 558767
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/558767
Therefore, the GCF of Fractions 906/643,253/869 is 1/558767
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 643,869 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,869) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,869) x common factors =1 x 1 = 1
LCM(643,869) = ( 643 × 869 ) / 1
LCM(643,869) = 558767 / 1
LCM(643,869) = 558767
