Greatest Common Factor
We found the factors 504,423 . The biggest common factor number is the GCF number.
So the greatest common factor 504,423 is 9.
Lets's calculate LCM of 930,452
2 | 930, 452 |
465, 226 |
∴ So the LCM of the given numbers is 2 x 465 x 226 = 210180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/210180
Therefore, the GCF of Fractions 504/930,423/452 is 9/210180
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 930,452 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(930,452) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(930,452) x common factors =2 x 1 = 2
LCM(930,452) = ( 930 × 452 ) / 2
LCM(930,452) = 420360 / 2
LCM(930,452) = 210180
