To find pairs of numbers with 10 as their least common multiple, we need to consider the prime factors of 10, which are 2 and 5. One pair of numbers could be 2 and 10, as their least common multiple is 10. Another pair could be 5 and 10, as their least common multiple is also 10. These pairs have 10 as their least common multiple because they share the prime factors of 10.

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.

You need at least two numbers to find an LCM and there can only be one least common. If you want to know multiples of 105, just keep adding 105. 105, 210, 315 and so on.

The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.

All pairs have the same same number of multiples: [countably] infinitely many.

Oh, dude, let me break it down for you. So, if the greatest common factor (GCF) is 7 and the least common multiple (LCM) is 210, the number pairs would be multiples of 7 that multiply to 210. So, the number pairs would be 7 and 210. That's it. Easy peasy lemon squeezy.

Pick any two numbers. All pairs of numbers have an LCM.

There are many common multiples of 120 and 149. A common multiple is simply a multiple of both numbers. The least common multiple is 120x149, since 149 is prime. (Note: this trick doesn't work on all pairs of number. Although the product is always a multiple, it's not the least common multiple.)
