Greatest Common Factor
We found the factors 72,24,123 . The biggest common factor number is the GCF number.
So the greatest common factor 72,24,123 is 3.
Lets's calculate LCM of 54,446,711
2 | 54, 446, 711 |
3 | 27, 223, 711 |
3 | 9, 223, 237 |
3, 223, 79 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 223 x 79 = 951318
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/951318
Therefore, the GCF of Fractions 72/54,24/446,123/711 is 3/951318
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 54,446,711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(54,446,711) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(54,446,711) x common factors =1 x 18 = 18
LCM(54,446,711) = ( 54 × 446 × 711 ) / 18
LCM(54,446,711) = 17123724 / 18
LCM(54,446,711) = 951318
