Common factors of 6, 9, and 36 are: 1 and 3.
The common factors of 9 and 7 are the numbers that can evenly divide both 9 and 7 without leaving a remainder. In this case, the only common factor of 9 and 7 is 1, as 9 is a prime number and only has 1 and itself as factors. Therefore, the common factors of 9 and 7 are 1.
There are no common factors of 126 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126. The prime factors of 126 are 2, 3, 3, and 7. Examples: The common factors of 4 and 126 are 1 and 2. The common factors of 36 and 126 are 1, 2, 3, 6, 9, and 18. The common factors of 49 and 126 are 1 and 7. The common factors of 12, 30, and 126 are 1, 2, 3, and 6.
The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The common factors of 6 and 9 are 1 and 3. Therefore, the least (smallest) common factor is 1.
