Greatest Common Factor
We found the factors 821,386 . The biggest common factor number is the GCF number.
So the greatest common factor 821,386 is 1.
Lets's calculate LCM of 65,7435
| 5 | 65, 7435 |
| 13, 1487 |
∴ So the LCM of the given numbers is 5 x 13 x 1487 = 96655
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/96655
Therefore, the GCF of Fractions 821/65,386/7435 is 1/96655
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 65,7435 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,7435) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,7435) x common factors =5 x 1 = 5
LCM(65,7435) = ( 65 × 7435 ) / 5
LCM(65,7435) = 483275 / 5
LCM(65,7435) = 96655
