So the greatest common factor 405,735 is 15.
Lets's calculate LCM of 16,4098
2 | 16, 4098 |
8, 2049 |
∴ So the LCM of the given numbers is 2 x 8 x 2049 = 32784
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/32784
Therefore, the GCF of Fractions 405/16,735/4098 is 15/32784
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 16,4098 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,4098) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(16,4098) x common factors =2 x 1 = 2
LCM(16,4098) = ( 16 × 4098 ) / 2
LCM(16,4098) = 65568 / 2
LCM(16,4098) = 32784
