Lets's calculate LCM of 776,892
2 | 776, 892 |
2 | 388, 446 |
194, 223 |
∴ So the LCM of the given numbers is 2 x 2 x 194 x 223 = 173048
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/173048
Therefore, the GCF of Fractions 420/776,118/892 is 2/173048
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 776,892 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(776,892) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(776,892) x common factors =4 x 1 = 4
LCM(776,892) = ( 776 × 892 ) / 4
LCM(776,892) = 692192 / 4
LCM(776,892) = 173048
