The multiples of nine are numbers that can be divided evenly by nine. To find the multiples of nine up to 200, you would simply continue multiplying nine by whole numbers until the result exceeds 200. The multiples of nine up to 200 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, and 198.
9
That the sum of its digits add up to 9 as for example 9*9 = 81 and 8+1 = 9
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
8 and 9 are corpime, so their first common multiple is their product. The next common multiples are simply the multiples of that first multiple.The first three common multiples are therefore 72, 144 and 216.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
The first two multiples are 9 and 8.
8 x 9 = 72 18 x 4 = 72
The common multiples of 8 and 9 are numbers that are divisible by both 8 and 9. To find the common multiples, you can list out the multiples of each number and identify the numbers that appear in both lists. The common multiples of 8 and 9 include 72, 144, 216, and so on, as these numbers are divisible by both 8 and 9.
