1 and 3 are.
The common factors of 6, 21, and 39 are 1 and 3
The common factors of 9, 21, and 24 are: 1 and 3
1 and 3 are common factors of 9 and 21
9 and 21 only have two common factors: 1 and 3.
Answer: 1 The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3; the least (smallest) common factor is 1.
The factors of 21 are: 1, 3, 7, 21.The factors of 27 are: 1, 3, 9, 27.The common factors are: 1, 3
Oh, dude, the common factors of 9 and 21 are the numbers that can divide both of them without leaving a remainder. So, the factors of 9 are 1, 3, and 9, while the factors of 21 are 1, 3, 7, and 21. The common factors between them are 1 and 3. Cool, right?
Since 21 is a factor of 63, all of its factors are common.
1 and 3 are both common factors of 9 and 21.
The greatest common factor is 3: Factors of 9: 1, 3, 9 Factors of 18: 1, 2, 3, 6, 9, 18 Factors of 21: 1, 3, 7, 21 The two common factors are 1 and 3 and the greatest of these two is 3.
They both have 1 and 3 as common factors
Oh, dude, the greatest common factor of 9, 15, and 21 is 3. It's like the superhero that swoops in to save the day, dividing all those numbers without breaking a sweat. So yeah, 3 is the chosen one in this math problem.
