No, for any number n greater than zero, the LCM of n and n is n.

If it's a whole-number "multiple" and the number itself is positive, then the multiple is always greater than the number itself.

No.

Greater than or equal to, yes. 10 is a multiple of 10.

You need at least two numbers to find an LCM. The lowest multiple of any positive number is the number itself.

Not necessarily. A number is also a multiple of itself.

The common multiple refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The "common" multiple of a number is itself.

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.

The LCM is the greater number.

The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.

False.

The common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.

The greatest common multiple of any set of integers is infinite.

The greater number.

Their product.

7 and 10

The greatest common FACTOR of 90 and 108 is 18. The LEAST common multiple is 540. There can be no greatest common multiple since double that number will be a greater common multiple.

That is impossible to answer, because you would have to have another number and 6 to find a least COMMON multiple.

The least common multiple of 11 and 22 is 22.

The least common multiple of 62 , 22 = 682

The least common multiple (LCM) refers to a multiple that is COMMON to two or more different numbers. You have only one number in the question! The least multiple of a number is itself.

280

This is the lowest common multiple which is the smallest number greater than 0 which is a multiple of all the numbers. for example the lowest common multiple (lcm) of 4 and 6 is 12 as 12 is the first (smallest) number greater than 0 that is a multiple of both 4 and 6.
