If restricted to integers, the answer is 1 - for any prime number.
That would depend entirely on the given number.
Two pairs of numbers with 105 as their least common multiple are (15, 105) and (21, 105). This means that both pairs of numbers are multiples of 105 and their only common multiple is 105. The least common multiple is the smallest number that both numbers can divide evenly into.
3, 10
4 and 9 12 and 18
4 and 9 12 and 17
9 and 12 12 and 18
18 and 36 12 and 36
15,4 10,60
1 and 36 or 2 and 36 are two possible pairs.
15 and 21 21 and 35
2 and 5 5 and 10
(3, 36) and (4, 9)
