So the greatest common factor 619,645 is 1.
Lets's calculate LCM of 17,8626
Given numbers has no common factors except 1. So, there LCM is their product i.e 146642
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/146642
Therefore, the GCF of Fractions 619/17,645/8626 is 1/146642
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 17,8626 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,8626) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,8626) x common factors =1 x 1 = 1
LCM(17,8626) = ( 17 × 8626 ) / 1
LCM(17,8626) = 146642 / 1
LCM(17,8626) = 146642
