So the greatest common factor 22,19,117 is 1.
Lets's calculate LCM of 385,238,905
5 | 385, 238, 905 |
7 | 77, 238, 181 |
11, 34, 181 |
∴ So the LCM of the given numbers is 5 x 7 x 11 x 34 x 181 = 2369290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2369290
Therefore, the GCF of Fractions 22/385,19/238,117/905 is 1/2369290
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 385,238,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(385,238,905) = 1
common factors(in case of two or more numbers have common factors) = 35
GCF(385,238,905) x common factors =1 x 35 = 35
LCM(385,238,905) = ( 385 × 238 × 905 ) / 35
LCM(385,238,905) = 82925150 / 35
LCM(385,238,905) = 2369290
