112 and 2 are 2 numbers
There are no two real numbers that do. Using complex numbers, these two do: (-3/2 + i√151/2) & (-3/2 - i√151/2) Two numbers that add to -3 and multiply to -40 are -8 & 5 Two numbers that add to 3 and multiply to -40 are 8 & -5 Two complex numbers that add to 3 and multiply to 40 are (3/2 + i√151/2) & (3/2 - i√151/2)
Write the numbers out in their prime factorisations in power format, then multiply together the highest power of all the prime numbers taken across both the numbers:24 = 23 x 396 = 25 x 3lcm = 25 x 3 = 96Alternatively, write out the multiples of the numbers, and spot the first common one:24: 24, 48, 72, 96, 120, ...96: 96, 192, ...(You may notice that 96 = 4 x 24 so the lcm will be 96.)
