The factors of 21 are 1 x 3 x 7 x 21.
The factors of 28 are 1 x 2 x 4 x 7 x 14 x 28.
The GCF of 21 and 28 is 7.
15, 30 and 45 have a GCF of 15.
The prime numbers between 15 and 30 are: 17 19 23 29.
The GCF is 15.
The GCF of 20 and 40 is 20 The GCF of 15 and 30 is 15 The GCF of 15, 20, 30 and 40 is 5.
Halfway between 15 and 30 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (15 + 30) / 2 = 45 / 2 = 22.5. Therefore, 22.5 is halfway between 15 and 30.
15, 30 and 45 have a GCF of 15.
