Greatest Common Factor
We found the factors 16,126,644 . The biggest common factor number is the GCF number.
So the greatest common factor 16,126,644 is 2.
Lets's calculate LCM of 72,26,289
2 | 72, 26, 289 |
36, 13, 289 |
∴ So the LCM of the given numbers is 2 x 36 x 13 x 289 = 270504
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/270504
Therefore, the GCF of Fractions 16/72,126/26,644/289 is 2/270504
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 72,26,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,26,289) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(72,26,289) x common factors =1 x 2 = 2
LCM(72,26,289) = ( 72 × 26 × 289 ) / 2
LCM(72,26,289) = 541008 / 2
LCM(72,26,289) = 270504
