They are: 2 and 9, 1 and 18
Two pairs of #'s with 10 as their least common multiple: 5x2 1x10
21 and 35 7 and 15
5 and 21 15 and 7 35 and 3
(3, 36) and (4, 9)
The factors of 10 are 1, 2, 5, and 10. The pair of numbers, of which the least common multiple is 10, must be made up of the factors of 10. Possibilities include: 2, 5 1, 10 2, 10 5, 10
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
