45, yes.
50, no.
All but 50.
Yes to all but 50.
No.
42, 45 and 48
Yes, 3 is a factor of 45 because 45 is divisible by 3. 45 = 3 x 15 + 0.
One way to approach this is to look at the difference between 45 and 50, which is 5. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 45 and 50 are divisible by 5, the greatest common factor is 5. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 45 are 3, 3, and 5. The prime factors of 50 are 2, 5, and 5. The prime factors in common are a single 5, so the greatest common factor is 5.
The GCF of 3 and 45 is 3.Since 3 is a factor of 45, it is automatically the GCF.
Since 3 is a factor of 45, it is automatically the GCF.

Yes.
The Highest Common Factor (HCF) of 50 and 45 is 5. To find the HCF, you can list the factors of each number and identify the greatest number that divides both 50 and 45 without leaving a remainder. In this case, the common factors of 50 are 1, 2, 5, 10, 25, and 50, while the common factors of 45 are 1, 3, 5, 9, 15, and 45. The highest common factor among these is 5.
48. 50 minus 45/9 = 50 - 5 = 45, 45 + 3 = 48
