Greatest Common Factor
We found the factors 412,691 . The biggest common factor number is the GCF number.
So the greatest common factor 412,691 is 1.
Lets's calculate LCM of 561,812
Given numbers has no common factors except 1. So, there LCM is their product i.e 455532
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/455532
Therefore, the GCF of Fractions 412/561,691/812 is 1/455532
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 561,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,812) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(561,812) x common factors =1 x 1 = 1
LCM(561,812) = ( 561 × 812 ) / 1
LCM(561,812) = 455532 / 1
LCM(561,812) = 455532
