Greatest Common Factor
We found the factors 246,149,671 . The biggest common factor number is the GCF number.
So the greatest common factor 246,149,671 is 1.
Lets's calculate LCM of 68,20,487
2 | 68, 20, 487 |
2 | 34, 10, 487 |
17, 5, 487 |
∴ So the LCM of the given numbers is 2 x 2 x 17 x 5 x 487 = 165580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/165580
Therefore, the GCF of Fractions 246/68,149/20,671/487 is 1/165580
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 68,20,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,20,487) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(68,20,487) x common factors =1 x 4 = 4
LCM(68,20,487) = ( 68 × 20 × 487 ) / 4
LCM(68,20,487) = 662320 / 4
LCM(68,20,487) = 165580
