One is the only factor that is common to both of those numbers.Factors of 28: 1 2 4 7 14 28Factors of 45: 1 3 5 9 15 45The GCF of 28 and 45 is 1Another way to approach this is to look at the difference between 28 and 45, which is 17. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. The greatest common factor of two numbers must also be a factor of the difference between the numbers. The difference, 17, is a prime number, so the greatest common factor must be either 17 or 1. Since the numbers are not evenly divisible by 17, the greatest common factor is 1.
23 is the only prime number between 20 and 28.

17.
The difference is 28 + 11 = 39 degrees.

Your answer is 52. The reason for this is because the difference between 7 and 10 is 3. The difference between 10 and 16 is 6. The difference between 16 and 28 is 12. So the last one must be 28 +24 = 52
The difference is 12 degrees.
Twice 22 is 44 The difference between 75 and 28 is 47 47+44=91
It is 28, the difference between the two numbers.
37, this sequence counts up from 5 the difference between 2 and 7. the difference between 20 and 28 is 8 making the next number 9, and 28 and 9 = 37.
The idea is to first do the subtraction, then multiply the result by 2.
