So the greatest common factor 82,21,786 is 1.
Lets's calculate LCM of 398,732,374
2 | 398, 732, 374 |
199, 366, 187 |
∴ So the LCM of the given numbers is 2 x 199 x 366 x 187 = 27239916
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27239916
Therefore, the GCF of Fractions 82/398,21/732,786/374 is 1/27239916
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 398,732,374 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,732,374) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(398,732,374) x common factors =2 x 2 = 4
LCM(398,732,374) = ( 398 × 732 × 374 ) / 4
LCM(398,732,374) = 108959664 / 4
LCM(398,732,374) = 27239916
