For LCM, we take the highest powers of each prime number and then multiply them.
The highest power of 2 in this case os 3, the highest power of 3 is 1 and the highest power of 7 is 3, so the LCM is 8232.
For the perfect square, we need to 'distribute' the contents of the 1029 into two identical brackets. We see that the second bracket needs an extra 3 and an extra 7 to complete the identical brackets, so k must contain a 3 and a 7.
