If it's a whole-number "multiple" and the number itself is positive,then the multiple is always greater than the number itself.
Greater than or equal to, yes. 10 is a multiple of 10.
negative Example would be. 0.1x0.1=0.01
There is no greatest multiple of any number: whatever multiple of 4 you say is the greatest I can always add 4 and get an even greater multiple.
No, not when negative numbers are involved. For example, -2 is a multiple of both -1 and 1 and is not greater than either.
There is NO greatest common multiple because I can always add another lowest common multiple and get an ever greater number that is a common multiple.
No. Whatever multiple of the number you think might be the limit, you can always add the whole number again and have a larger multiple.
No, it is a factor. Multiples are always greater than the number itself, factors are smaller.
Not with negative numbers. -10 is a multiple of -2.
Not necessarily. A number is also a multiple of itself.
33 is the first composite number that is greater than 30 but is not a multiple of 2
The LCM is the greater number.
