The only common factor that 13 and 18 have is 1.
One way to determine common factors is to find all the factors of the numbers and compare them.
The factors of 13 are 1 and 13.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The only common factor is 1.
Therefore, the least (smallest) common factor is 1 and the greatest (highest) common factor is 1.
The least common factor of any set of integers is 1.

What is the least common factor of 18 and 33?
The least common factor of 18 and 33 is 1.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 33 are 1, 3, 11, and 33.The common factors of 18 and 33 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.Note: Because the least common factor of two or more positive integers is always 1, this is not usually asked.trick questionThe least common factor is: 1The least common factor of any set of integers is 1.
What is the least common factor of 12 and 18?
If you want the "least", then there can only be one. If there were more than one,then one would be smaller than the other, and they wouldn't both be "least".The least common factor of 12 and 18 is ' 1 '.In fact, the least common factor of any two numbers is ' 1 '.
What is the least common factor of 6 and 18?
The factors of 6 are 1, 2, 3, and 6. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 6 and 18 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
What is the least common factor of 18 and 21?
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1. Factorizations: 18-3x3x2 21-7x3
What is the least common multiple of 18 and 72?
The least common multiple of 18 and 72 is 72. Since 18 is a factor of 72, 72 is automatically the LCM of the pair.
