The GCF is 63.
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. To find the GCF of 28 and 63, we need to list the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28, while the factors of 63 are 1, 3, 7, 9, 21, and 63. The largest number that appears in both lists is 7, so the GCF of 28 and 63 is 7.
To find the highest common factor of 441 and 378, we first need to factorize both numbers. The factors of 441 are 3 x 3 x 7 x 7, and the factors of 378 are 2 x 3 x 3 x 3 x 7. The common factors between the two numbers are 3 x 3 x 7, which equals 63. Therefore, the highest common factor of 441 and 378 is 63.
To find the greatest common factor (GCF) of 28, 42, and 63, we first need to find the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The GCF of 28, 42, and 63 is the largest number that appears in the factor lists of all three numbers, which is 7.
The common factors of 28 and 63 are: 1 and 7
The Greatest Common Factor of 28, 42, 63: 7
The greatest common factor of the numbers 28, 35 and 63 is 7.
The highest common factor is 9
The greatest common factor of the numbers 63 and 15 is 3.
The GCF is 7.
The highest common factor is 21
The highest common factor of 36 and 63 is 9
225 = 3252 63 = 327 so the greatest common factor is 9
The GCF (Greatest Common Factor) of 63 and 98 is: 7
The Greatest Common Factor (GCF) is: 3
The Greatest Common Factor (GCF) is: 9
The Greatest Common Factor (GCF) is: 9
