No. 6 is not a factor of 15. The greatest common factor of 15 and 18 is 3.
The GCF is 9.
You need at least two numbers to find a GCF. The GCF of 18 and 24 is 6.
3 and 18
9 and 6 have an LCM of 18 and a GCF of 3.
18, 36, 54
No. 6 is not a factor of 15. The greatest common factor of 15 and 18 is 3.
9, 18 and 27
The GCF of the given numbers is 3
15 and 18
The GCF of 3, 12, and 18 is 3
The GCF is 9.
The GCF of 9, 18, and 42 is 3.The factors of 9 = 3*3The factors of 18 = 2*3*3The factors of 42 = 2*3*7So the greatest common factor = 3.
The GCF of 18 and 3 = 3
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 18 and 21, you can list the factors of each number: 18 (1, 2, 3, 6, 9, 18) and 21 (1, 3, 7, 21). The common factors are 1 and 3, and the greatest common factor is 3.
