I'll guess those are three-digit numbers. The way to find if a number is a multiple of 3 is to total its digits. If that total is a multiple of 3, the whole number is a multiple of 3.
285 and 126, yes.
770, 176, 410, 452, 650, no.
4 is a multiple of three numbers.
If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.
A multiple of 3 Also a multiple of 6.
3,6,9,12,15,18,21,24,27,30,33,36,39,42,46,49,52,55,58,61,64,67,80,83,86,89,92, 95,98 and 101 They are all the numbers I know. XD
These do exist.
128
Calculate the least common multiple of the three numbers. Any multiple of that has all those numbers as factors.
EVERY three consecutive numbers add to a multiple of 3: Proof: numbers are n, n + 1 and n + 2. The total is 3n + 3 or 3(n + 1) This means that for any three consecutive numbers, the total is 3 times the middle number.
The answer is 9 × 6 × 7

That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
