The largest multiple of anything is infinite.
12
There are four of them...
-- Every multiple of 12 has a remainder of 3 when divided by 9.-- The largest multiple of 12 that's less than 220 is (12 x 18) = 216.-- So there are 18 of them.

The highest common factor of 6 and 8 is always 2 - it has to be less than or equal to the smaller of the two numbers.If you mean the highest common multiple of 6 and 8 less than 100, then it is 96.All common multiples of 6 and 8 are multiples of their Lowest Common Multiple.The LCM(6, 8) = 24, thus all common multiples of 6 and 8 are multiples of 24.The largest one less than 100 is:100 ÷ 24 = 41/6⇒ highest multiple of 24 less than 100 is 4 x 24 = 96.
4 x 5 = 20
The multiples of 4 that are less than 30 are 4, 8, 12, 16, 20, 24, 28. So the greatest multiple of 4 that is less than 30 is 28.
6 12 18 24 30
104 ÷ 24 = 4 with remainder 8 or 4.33
To find the multiples of 8 that are less than 60, we can start by dividing 60 by 8, which equals 7 with a remainder of 4. This means that the largest multiple of 8 less than 60 is 8 x 7 = 56. Therefore, the multiples of 8 that are less than 60 are 8, 16, 24, 32, 40, 48, and 56.
