So the greatest common factor 812,786 is 2.
Lets's calculate LCM of 78,786
2 | 78, 786 |
3 | 39, 393 |
13, 131 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 131 = 10218
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10218
Therefore, the GCF of Fractions 812/78,786/786 is 2/10218
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 78,786 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,786) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(78,786) x common factors =6 x 1 = 6
LCM(78,786) = ( 78 × 786 ) / 6
LCM(78,786) = 61308 / 6
LCM(78,786) = 10218
