Question 60

The LCM and HCF of two numbers are 4284 and 32, respectively. If one of the numbers is 672, then the second number is;

Solution

HCF is 32

LCM is 4284

Let the other number be x

We know that HCF * LCM = produce of 2 numbers.

$$32\times 4284 = 672 \times x$$

$$x =\frac{32\times4284}{672}$$

$$x = 204$$

Option C is correct.
