So the greatest common factor 54,28,858 is 2.
Lets's calculate LCM of 235,918,423
3 | 235, 918, 423 |
3 | 235, 306, 141 |
47 | 235, 102, 47 |
5, 102, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 47 x 5 x 102 x 1 = 215730
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/215730
Therefore, the GCF of Fractions 54/235,28/918,858/423 is 2/215730
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 235,918,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(235,918,423) = 1
common factors(in case of two or more numbers have common factors) = 423
GCF(235,918,423) x common factors =1 x 423 = 423
LCM(235,918,423) = ( 235 × 918 × 423 ) / 423
LCM(235,918,423) = 91253790 / 423
LCM(235,918,423) = 215730
