Greatest Common Factor
We found the factors 84,40,589 . The biggest common factor number is the GCF number.
So the greatest common factor 84,40,589 is 1.
Lets's calculate LCM of 62,83,490
2 | 62, 83, 490 |
31, 83, 245 |
∴ So the LCM of the given numbers is 2 x 31 x 83 x 245 = 1260770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1260770
Therefore, the GCF of Fractions 84/62,40/83,589/490 is 1/1260770
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 62,83,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,83,490) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(62,83,490) x common factors =1 x 2 = 2
LCM(62,83,490) = ( 62 × 83 × 490 ) / 2
LCM(62,83,490) = 2521540 / 2
LCM(62,83,490) = 1260770
