2 x 2 x 2 x 5 = 40
If the number is odd, that's the answer. If the number is even, write down all the factors and choose the largest one that is odd.
To find the highest common factor of two numbers you first need to break them down into their prime factors. In this case: 24 = 2x2x2x3 28 = 2x2x7 The next step is to identify the common factors. In this case, both numbers have two 2s as a factor. We multiply these together to get the HCF: 2x2=4 Thus 4 is the highest common factor of 24 and 28.
The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor is the largest factor common to two or more numbers.
To find the highest common factor you first need to break the numbers down into their prime factors. In this case 34 and 58 are broken down as follows: 34 = 2x17 58 = 2x29 The next step is to identify any common prime factors. In this case, the only common prime factor is a single 2. Therefore the highest common factor of 34 and 58 is 2.
Select two numbers. List their factors. Write down the numbers that appear on both lists. Choose the largest one. That's the GCF.
It is 34 parts of 100, so it starts as 34 over 100. It can be simplified, by dividing by the highest common factor of the two numbers. The highest common factor is 2. Divide by 2 gives 17 over 50.
Oh, what a happy little question! To find the highest common factor of 119 and 203, we can first find the factors of each number. The factors of 119 are 1, 7, 17, and 119, while the factors of 203 are 1, 7, 29, and 203. The highest common factor is 7, a lovely number that both 119 and 203 share.
2 x 2 x 2 x 5 = 40
List the factors of the numbers you're comparing. Write down the numbers that appear on both lists. Those are the common factors.
If the number is odd, that's the answer. If the number is even, write down all the factors and choose the largest one that is odd.
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! There is, therefore no GCF and so answer to the question.
The greatest common factor of 21 and 27 is 3 because that is the highest number that goes into 21 and 27. To find the highest common factor of two numbers, you first have to break them down into their prime factors. In this case, the prime factors of 21 and 27 are: 21 = 3x7 27 = 3x3x3 The next step is to identify any common factors. In this case, the only common prime factor is 3. Thus, the highest common factor of 21 and 27 is 3.
The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The factors of 210 are:1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210The Greatest Common Factor:GCF = 42
Write down the factors of the numbers you're comparing. Choose the largest number that appears on both lists.
The LCM is 12.
