Greatest Common Factor
We found the factors 825,249 . The biggest common factor number is the GCF number.
So the greatest common factor 825,249 is 3.
Lets's calculate LCM of 428,221
Given numbers has no common factors except 1. So, there LCM is their product i.e 94588
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/94588
Therefore, the GCF of Fractions 825/428,249/221 is 3/94588
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 428,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,221) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(428,221) x common factors =1 x 1 = 1
LCM(428,221) = ( 428 × 221 ) / 1
LCM(428,221) = 94588 / 1
LCM(428,221) = 94588
