So the greatest common factor 84,789,598 is 1.
Lets's calculate LCM of 68,14,357
2 | 68, 14, 357 |
7 | 34, 7, 357 |
17 | 34, 1, 51 |
2, 1, 3 |
∴ So the LCM of the given numbers is 2 x 7 x 17 x 2 x 1 x 3 = 1428
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1428
Therefore, the GCF of Fractions 84/68,789/14,598/357 is 1/1428
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 68,14,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,14,357) = 1
common factors(in case of two or more numbers have common factors) = 238
GCF(68,14,357) x common factors =1 x 238 = 238
LCM(68,14,357) = ( 68 × 14 × 357 ) / 238
LCM(68,14,357) = 339864 / 238
LCM(68,14,357) = 1428
