So the greatest common factor 86,282,397 is 1.
Lets's calculate LCM of 18,98,348
2 | 18, 98, 348 |
3 | 9, 49, 174 |
3, 49, 58 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 49 x 58 = 51156
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51156
Therefore, the GCF of Fractions 86/18,282/98,397/348 is 1/51156
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 18,98,348 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,98,348) = 2
common factors(in case of two or more numbers have common factors) = 6
GCF(18,98,348) x common factors =2 x 6 = 12
LCM(18,98,348) = ( 18 × 98 × 348 ) / 12
LCM(18,98,348) = 613872 / 12
LCM(18,98,348) = 51156
