You need at least two numbers to find something in common between them, but I'll save you the trouble. The least common factor of any set of integers is 1.
The factors of 8 are 1, 2, 4, and 8. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 8 and 16 are 1, 2, 4, and 8. The least (smallest) common factor is 1.
The least common multiple of 16 and 8 is 16. Because 16 is a multiple of 8, it is automatically the LCM of the pair. Another approach: To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 8 are 2 x 2 x 2. The prime factors of 16 are 2 x 2 x 2 x 2.
The least common factor of any set of numbers is 1.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest common factor) is 1.
You need at least two numbers to find something in common.
16 and 32
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
There cannot be a common factor of just one number. To be common there need to be at least two numbers.The term common factors specifically refers to the factors shared by two or more numbers. Since 16 is a single number, you could say that it shares all of its factors with itself.The factors of 16 are: 1, 2, 4, 8, and 16.
There cannot be a common factor of just one number. To be common there need to be at least two numbers.
There cannot be a common factor of just one number. To be common there need to be at least two numbers.
