Iam thinking of a number my number a multiple of 6 what three other multiples must my number be a multiple of

If it is a multiple of 6 then it can be written as this the number you are thinking of=6k. 6=2*3 => x=2*3k. If your number is a multiple of six than it is a normal number - every normal number is a multiple of 1 (obviously)=> x=1*2*3k So the number you are thinking of is a multiple to 1, 2 and 3. Hope this helped!
