So the greatest common factor 425,640 is 5.
Lets's calculate LCM of 454,663
Given numbers has no common factors except 1. So, there LCM is their product i.e 301002
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/301002
Therefore, the GCF of Fractions 425/454,640/663 is 5/301002
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 454,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(454,663) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(454,663) x common factors =1 x 1 = 1
LCM(454,663) = ( 454 × 663 ) / 1
LCM(454,663) = 301002 / 1
LCM(454,663) = 301002
