Lets's calculate LCM of 873,568,392
2 | 873, 568, 392 |
2 | 873, 284, 196 |
2 | 873, 142, 98 |
873, 71, 49 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 873 x 71 x 49 = 24297336
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24297336
Therefore, the GCF of Fractions 73/873,680/568,686/392 is 1/24297336
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 873,568,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(873,568,392) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(873,568,392) x common factors =1 x 8 = 8
LCM(873,568,392) = ( 873 × 568 × 392 ) / 8
LCM(873,568,392) = 194378688 / 8
LCM(873,568,392) = 24297336
