63

A common multiple of 9 and 21 is 63

To find the least common multiple (LCM) of 9, 21, and 7, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3*7, and 7 is a prime number itself. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 3^2 * 7 = 63. Therefore, the least common multiple of 9, 21, and 7 is 63.

The lowest common multiple of 7 and 9 is 63.Here's how to work it out:Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...Multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...To find the lowest common multiple you look and find the smallest number that is a multiple of both numbers (in your case 7 and 9). So, in this case the lowest multiple they both have in common is 63.637963The Least Common Multiple (LCM) for 7 9 is 63.
