So the greatest common factor 56,206,989 is 1.
Lets's calculate LCM of 494,195,810
2 | 494, 195, 810 |
3 | 247, 195, 405 |
5 | 247, 65, 135 |
13 | 247, 13, 27 |
19, 1, 27 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 13 x 19 x 1 x 27 = 200070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/200070
Therefore, the GCF of Fractions 56/494,206/195,989/810 is 1/200070
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 494,195,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(494,195,810) = 1
common factors(in case of two or more numbers have common factors) = 390
GCF(494,195,810) x common factors =1 x 390 = 390
LCM(494,195,810) = ( 494 × 195 × 810 ) / 390
LCM(494,195,810) = 78027300 / 390
LCM(494,195,810) = 200070
