The first step to identifying the least common multiples is to break the numbers down into their prime factors. However in this case both numbers (13 and 17) are prime so cannot be broken down any further. Thus you simply take the numbers and multiply them together:
13 x 17 = 221
Thus 221 is the least common multiple of 13 and 17.
