Lets's calculate LCM of 756,892
2 | 756, 892 |
2 | 378, 446 |
189, 223 |
∴ So the LCM of the given numbers is 2 x 2 x 189 x 223 = 168588
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/168588
Therefore, the GCF of Fractions 423/756,868/892 is 1/168588
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 756,892 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(756,892) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(756,892) x common factors =4 x 1 = 4
LCM(756,892) = ( 756 × 892 ) / 4
LCM(756,892) = 674352 / 4
LCM(756,892) = 168588
