Greatest Common Factor
We found the factors 85,90,856 . The biggest common factor number is the GCF number.
So the greatest common factor 85,90,856 is 1.
Lets's calculate LCM of 99,79,249
3 | 99, 79, 249 |
33, 79, 83 |
∴ So the LCM of the given numbers is 3 x 33 x 79 x 83 = 649143
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/649143
Therefore, the GCF of Fractions 85/99,90/79,856/249 is 1/649143
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 99,79,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,79,249) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(99,79,249) x common factors =1 x 3 = 3
LCM(99,79,249) = ( 99 × 79 × 249 ) / 3
LCM(99,79,249) = 1947429 / 3
LCM(99,79,249) = 649143
