The greatest common factor (GCF) for 9 and 21 is 3.
3
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.
21 = 7 x 3 , 9 = 3 x 3 ; for the Least Common Multiple (LCM), 21 already is a multiple of 7. 21 & 9 have a common factor of 3, so LCM = 21 x 3 = 63
Since 9 is a factor of 63, all of its factors are common.
The Greatest Common Factor of 9, 18, 21: 3
The Greatest Common Factor of 60, 21, 9: 3
The Greatest Common Factor of 21, 9 is 3.
The greatest common factor (GCF) of 21 and 9 is 3.
1 and 3 are both common factors of 9 and 21.

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 greatest common factor (GCF) for 9 and 21 is 3.
They both have 1 and 3 as common factors
3
The GCF of 21 and 9 is 3. 21 and 9 can only be divided by three.
They are 1 and 3 .Note: Those are also the least common factors of 9, 21, and 54 .
