Can a LCM be one

Answer 1

Yes, if the the number you are finding the LCM of is 1. But usually, LCM involves two or more numbers. While finding the LCM of one number is uncommon and technically an incorrect practice, it is possible.

Answer 2

Yes, but very rarely. The LCM of (1,1) is one.

Answer 3

You need at least two numbers to find an LCM, but the LCM of 1 and any other positive integer will be the other integer.

Answer 4

The only way the LCM of three numbers could be one of the numbers is if the other two numbers are factors of it. The LCM of 4, 8 and 16 is 16.

Answer 5

No. The LCM cannot be smaller than the largest number in the set.

Answer 6

No. The LCM has to be equal to or greater than the largest number in the set.

Answer 7

Only if you're comparing a number to itself. The GCF and LCM of 10 and 10 is 10.

Answer 8

It can, but only if the two numbers don't have any common factors other than 1. The LCM of 4 and 9 is 36.

Answer 9

The greater number.
