The factors of 9 are 1, 3 and 9. For them to be common, they need to be compared to another set of factors.
The common factors of 27 and 30 are 1, 3, and 9.
1 and 3.
since 9 and 11 have no common factors, the LCD is 99
least common denominator for 15 and 10 is 30, so 9/15 = 18/30 and 7/10 = 21/30
Common factors of 9, 15, and 30 are: 1 and 3.
The least common denominator is 30. 9/10 = 27/30
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 30 and 36 are 1, 2, 3, and 6. Therefore, the least common factor (the smallest common factor) is 1.
The least common multiple of the numbers 30, 15 and 9 is 90.
The factors of 9 are 1, 3 and 9. For them to be common, they need to be compared to another set of factors.
The common factors of 27 and 30 are 1, 3, and 9.
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.
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.
You can't find common factors of a single integer; you need at least two to compare in order to label the factors "common."
The GCF of 9 and 30 is 3.
1 and 3.
The factors of 9 are 1, 3, and 9. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 9 and 36 are 1, 3, and 9. Therefore, the least (smallest) common factor is 1.
