So the greatest common factor 669,430 is 1.
Lets's calculate LCM of 133,547
Given numbers has no common factors except 1. So, there LCM is their product i.e 72751
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72751
Therefore, the GCF of Fractions 669/133,430/547 is 1/72751
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 133,547 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(133,547) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(133,547) x common factors =1 x 1 = 1
LCM(133,547) = ( 133 × 547 ) / 1
LCM(133,547) = 72751 / 1
LCM(133,547) = 72751
