Lets's calculate LCM of 361,528,249
3 | 361, 528, 249 |
361, 176, 83 |
∴ So the LCM of the given numbers is 3 x 361 x 176 x 83 = 15820464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15820464
Therefore, the GCF of Fractions 39/361,18/528,821/249 is 1/15820464
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 361,528,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(361,528,249) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(361,528,249) x common factors =1 x 3 = 3
LCM(361,528,249) = ( 361 × 528 × 249 ) / 3
LCM(361,528,249) = 47461392 / 3
LCM(361,528,249) = 15820464
