16 is a factor of 48. Since the largest possible factor of 16 is 16 itself, the greatest common factor of 16 and 48 is 16.

The factors of 16 are 1, 2, 4, 8, and 16.

The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

The factors they have in common are 1, 2, 4, 8, and 16. Therefore, 16 is the greatest common factor.

The greatest common factor can also be determined from the prime factors.

The prime factors of 16 are 2, 2, 2, and 2.

The prime factors of 48 are 2, 2, 2, 2, and 3.

The prime factors they have in common are 2, 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 x 2 = 16.
