So the greatest common factor 54,20,917 is 1.
Lets's calculate LCM of 216,943,684
2 | 216, 943, 684 |
2 | 108, 943, 342 |
3 | 54, 943, 171 |
3 | 18, 943, 57 |
6, 943, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 6 x 943 x 19 = 3870072
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3870072
Therefore, the GCF of Fractions 54/216,20/943,917/684 is 1/3870072
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 216,943,684 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(216,943,684) = 1
common factors(in case of two or more numbers have common factors) = 36
GCF(216,943,684) x common factors =1 x 36 = 36
LCM(216,943,684) = ( 216 × 943 × 684 ) / 36
LCM(216,943,684) = 139322592 / 36
LCM(216,943,684) = 3870072
