Greatest Common Factor
We found the factors 493,653,278 . The biggest common factor number is the GCF number.
So the greatest common factor 493,653,278 is 1.
Lets's calculate LCM of 68,50,16
2 | 68, 50, 16 |
2 | 34, 25, 8 |
17, 25, 4 |
∴ So the LCM of the given numbers is 2 x 2 x 17 x 25 x 4 = 6800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6800
Therefore, the GCF of Fractions 493/68,653/50,278/16 is 1/6800
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 68,50,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,50,16) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(68,50,16) x common factors =2 x 4 = 8
LCM(68,50,16) = ( 68 × 50 × 16 ) / 8
LCM(68,50,16) = 54400 / 8
LCM(68,50,16) = 6800
