Question

The product of two numbers is 2208. If the lcm of the numbers is 552 what is their hcf

Answer 1

let the 2 numbers be "x" and "y" respectively

given
x × y = 2208
LCM = 552

solution

$lcm \times hcf = x \times y \\ 552 \times hcf = 2208 \\ hcf = 2208 \div 552 \\ hcf = 4$
therefore the HCF is 4
