So the greatest common factor 72,17,886 is 1.
Lets's calculate LCM of 812,285,812
2 | 812, 285, 812 |
2 | 406, 285, 406 |
7 | 203, 285, 203 |
29 | 29, 285, 29 |
1, 285, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 29 x 1 x 285 x 1 = 231420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/231420
Therefore, the GCF of Fractions 72/812,17/285,886/812 is 1/231420
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 812,285,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,285,812) = 1
common factors(in case of two or more numbers have common factors) = 812
GCF(812,285,812) x common factors =1 x 812 = 812
LCM(812,285,812) = ( 812 × 285 × 812 ) / 812
LCM(812,285,812) = 187913040 / 812
LCM(812,285,812) = 231420
