Greatest Common Factor
We found the factors 425,8981 . The biggest common factor number is the GCF number.
So the greatest common factor 425,8981 is 1.
Lets's calculate LCM of 812,3420
2 | 812, 3420 |
2 | 406, 1710 |
203, 855 |
∴ So the LCM of the given numbers is 2 x 2 x 203 x 855 = 694260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/694260
Therefore, the GCF of Fractions 425/812,8981/3420 is 1/694260
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 812,3420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,3420) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(812,3420) x common factors =4 x 1 = 4
LCM(812,3420) = ( 812 × 3420 ) / 4
LCM(812,3420) = 2777040 / 4
LCM(812,3420) = 694260
