We found the factors 712,706,678 . The biggest common factor number is the GCF number.
So the greatest common factor 712,706,678 is 2.
Lets's calculate LCM of 72,10,479
2 | 72, 10, 479 |
36, 5, 479 |
∴ So the LCM of the given numbers is 2 x 36 x 5 x 479 = 172440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/172440
Therefore, the GCF of Fractions 712/72,706/10,678/479 is 2/172440
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 72,10,479 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,10,479) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(72,10,479) x common factors =1 x 2 = 2
LCM(72,10,479) = ( 72 × 10 × 479 ) / 2
LCM(72,10,479) = 344880 / 2
LCM(72,10,479) = 172440
