So the greatest common factor 50,919,830 is 1.
Lets's calculate LCM of 78,18,181
2 | 78, 18, 181 |
3 | 39, 9, 181 |
13, 3, 181 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 3 x 181 = 42354
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42354
Therefore, the GCF of Fractions 50/78,919/18,830/181 is 1/42354
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 78,18,181 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,18,181) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(78,18,181) x common factors =1 x 6 = 6
LCM(78,18,181) = ( 78 × 18 × 181 ) / 6
LCM(78,18,181) = 254124 / 6
LCM(78,18,181) = 42354
