Greatest Common Factor
We found the factors 551,747 . The biggest common factor number is the GCF number.
So the greatest common factor 551,747 is 1.
Lets's calculate LCM of 409,717
Given numbers has no common factors except 1. So, there LCM is their product i.e 293253
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/293253
Therefore, the GCF of Fractions 551/409,747/717 is 1/293253
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 409,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(409,717) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(409,717) x common factors =1 x 1 = 1
LCM(409,717) = ( 409 × 717 ) / 1
LCM(409,717) = 293253 / 1
LCM(409,717) = 293253
