CF- 1, 3, 9
GCF- 9
Solution:
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 27 are: 1, 3, 9, 27
Therefore, the common factors of 18 and 27 are 1, 3 and 9.
Therefore, the greatest common factor of 18 and 27 is 9.
2. 21 and 35
CF- 1,7
GCF- 7
Solution:
The factors of 21 are: 1, 3, 7, 21
The factors of 35 are: 1, 5, 7, 35
Therefore, the common factors of 21 and 35 are 1, and 7.
Therefore, the greatest common factor of 21 and 35 is 7.
3. 24 and 36
CF- 1,2,3,4,6,12
GCF- 12
Solution:
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
Therefore, the common factors of 24 and 36 are 1, 2, 3, 4, 6, and 12.
Therefore, the greatest common factor of 24 and 36 is 12.
4. 12 and 18
CF- 12,3,6
GCF- 6
Solution:
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Therefore, the common factors of 12 and 18 are 1, 2, 3 and 6.
Therefore, the greatest common factor of 12 and 18 is 6.
5. 15 and 25
CF- 1,5
GCF- 5
Solution:
The factors of 15 are: 1, 3, 5, 15
The factors of 25 are: 1, 5, 25
Therefore, the common factors of 15 and 25 are 1, and 5.
Therefore, the greatest common factor of 15 and 25 is 5.
Additional Info!
A greatest common factor (GCF) is the highest common numer the one that are common to both and then choose the greatest common factor.
A common factor (CF) is a number that can be divided into two or more different numbers, that leaving with no remainder. It is possible to find the common factors of more than two numbers.
