Lets's calculate LCM of 756,121,393
3 | 756, 121, 393 |
252, 121, 131 |
∴ So the LCM of the given numbers is 3 x 252 x 121 x 131 = 11983356
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11983356
Therefore, the GCF of Fractions 67/756,21/121,426/393 is 1/11983356
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 756,121,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(756,121,393) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(756,121,393) x common factors =1 x 3 = 3
LCM(756,121,393) = ( 756 × 121 × 393 ) / 3
LCM(756,121,393) = 35950068 / 3
LCM(756,121,393) = 11983356
