What is the greatest common factor of 48 and 6?
Since 6 is a factor of 48, and 6 is the largest factor of itself, 6 is the greatest common factor. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 6 are 1, 2, 3, and 6. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The common factors are 1, 2, 3, and 6. Therefore, 6 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 6 are 2 and 3. The prime factors of 48 are 2, 2, 2, 2, and 3. The common prime factors are 2 and 3, so the greatest common factor is 2 x 3 = 6.
What is the greatest common factor of 30 and 1224?
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 30 are 2, 3, and 5. The prime factors 1224 are 2, 2, 2, 3, 3, and 17. The prime factors in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.
