63 = 3 x 3 x 7, so there are more than one combination: 7 & 9 and 21 & 9. That should be it, unless you want to consider the somewhat trivial combinations : 63 & 21, 63 & 9, 63 & 3, 63 & 7.

The two numbers whose least common multiple (LCM) is 63 are 9 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 9 and 7 are both prime numbers and their LCM is the product of the two numbers: 9 * 7 = 63.
Well, honey, the two numbers whose LCM is 63 are 9 and 7. You see, the LCM is the smallest number that both numbers divide into evenly, and in this case, 9 and 7 fit the bill. So, there you have it - 9 and 7 are the dynamic duo with an LCM of 63.
Oh, what a happy little question! To find two numbers whose Least Common Multiple (LCM) is 63, we can look for pairs of numbers that, when multiplied, equal 63. One such pair is 9 and 7, as their LCM is indeed 63. Remember, there are many combinations of numbers that can have 63 as their LCM, so feel free to explore and discover more!
10 and 63
The LCM of 14 and 63 is 126. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 14 and 63 is 7, so the least common multiple is 14 x 63 ÷ 7 = 126.
The least common multiple of the numbers 54, 63 and 108 is 756.
6 and 12
First you need to break the numbers into their prime factors. In this case we get: 63 = 3x3x7 21 = 3x7 The next step is to identify any common prime factors. In this case both have a 3 and a 7 as prime factors. Multiply these together and you get 3x7 = 21. This is the HCF. To find the LCM you just multiply the numbers together and divide by the HCF. 63x21/21 = 63 Thus 63 is the LCM.
