So the greatest common factor 61,784,406 is 1.
Lets's calculate LCM of 55,20,457
5 | 55, 20, 457 |
11, 4, 457 |
∴ So the LCM of the given numbers is 5 x 11 x 4 x 457 = 100540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100540
Therefore, the GCF of Fractions 61/55,784/20,406/457 is 1/100540
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 55,20,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,20,457) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(55,20,457) x common factors =1 x 5 = 5
LCM(55,20,457) = ( 55 × 20 × 457 ) / 5
LCM(55,20,457) = 502700 / 5
LCM(55,20,457) = 100540
