Lets's calculate LCM of 654,389
Given numbers has no common factors except 1. So, there LCM is their product i.e 254406
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/254406
Therefore, the GCF of Fractions 290/654,8658/389 is 2/254406
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 654,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(654,389) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(654,389) x common factors =1 x 1 = 1
LCM(654,389) = ( 654 × 389 ) / 1
LCM(654,389) = 254406 / 1
LCM(654,389) = 254406
Here are some samples of GCF of Fractions calculations.
