So the greatest common factor 13,84,718 is 1.
Lets's calculate LCM of 245,189,684
3 | 245, 189, 684 |
3 | 245, 63, 228 |
7 | 245, 21, 76 |
35, 3, 76 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 35 x 3 x 76 = 502740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/502740
Therefore, the GCF of Fractions 13/245,84/189,718/684 is 1/502740
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 245,189,684 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(245,189,684) = 1
common factors(in case of two or more numbers have common factors) = 63
GCF(245,189,684) x common factors =1 x 63 = 63
LCM(245,189,684) = ( 245 × 189 × 684 ) / 63
LCM(245,189,684) = 31672620 / 63
LCM(245,189,684) = 502740
