It is: 6
The common factors of 42 and 273 are 1, 3, 7 and 21.
The common factors of 21 42 and 84 are 21
The common factors of 21, 42, and 56 are: 1 and 7
To work this out, you first have to split the numbers down into their prime factors: 42 = 2x3x7 23 = 23 There are no common prime factors. This means that the only common factor of 42 and 23 is 1.
It is: 6
It is 7
The GCF is 6.
The greatest common factor is 21
The factors of 30 are 2, 3, and 5 The factors of 42 are 2, 3, and 7 So, the highest common factor will be 2 x 3 = 6
The Greatest Common Factor (GCF) is: 6
The factors of 18 are: 1, 2, 3, 6, 9, 18.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The common factors are: 1, 2, 3, 6.The Greatest Common Factor (GCF) is: 6
To do this, the first step is to write the numbers as the product of their prime factors. In this case we have: 42 = 2x3x7 63 = 3x3x7 The next step is to identify common factors. In this case both numbers have a 3 and a 7 as factors. Take these numbers and multiply them together to find the HCF: 3x7 = 21 Thus the highest common factor of 42 and 63 is 21.
The highest common factor of all four numbers is 7
6 * 8 = 48 6 * 7 = 42 The highest common factor is 8.
Common factors of 42 and 87 are: 1 and 3.
The highest common factor (HCF) of 12 and 42 is the largest number that divides both 12 and 42 without leaving a remainder. To find the HCF, we need to determine the common factors of 12 and 42, which are 1, 2, 3, and 6. The highest common factor of 12 and 42 is 6.
