Lets's calculate LCM of 20,6368
2 | 20, 6368 |
2 | 10, 3184 |
5, 1592 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 1592 = 31840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/31840
Therefore, the GCF of Fractions 189/20,657/6368 is 9/31840
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 20,6368 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,6368) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(20,6368) x common factors =4 x 1 = 4
LCM(20,6368) = ( 20 × 6368 ) / 4
LCM(20,6368) = 127360 / 4
LCM(20,6368) = 31840
