Write down the greatest common factor of 80 and 200 in prime factor form?
2 x 2 x 2 x 5 = 40
How do you find highest odd factor of a number?
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.
What is the highest common factor of 24 and 28?
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.
How can you find the common factors and the greatest common factor of two numbers?
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
What is the greatest common factor of 1 and 18?
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.
The highest common factor of 34 and 58?
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.
How do you get the highest common factor?
Select two numbers. List their factors. Write down the numbers that appear on both lists. Choose the largest one. That's the GCF.
How do you break down 0.34 into a fraction?
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.
Write down the greatest common factor of 80 and 200 in prime factor form?
2 x 2 x 2 x 5 = 40
How to fine the common factor?
List the factors of the numbers you're comparing. Write down the numbers that appear on both lists. Those are the common factors.
What is the greatest common factor of 21 and 27?
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.
How do you Write 45 as a product of the GCF and another number?
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.
How do you find highest odd factor of a number?
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.
How do you find biggest common factor?
Write down the factors of the numbers you're comparing. Choose the largest number that appears on both lists.
What is the LCM of 12 6 and 3?
The LCM is 12.
What is the highest common factor of 24 and 28?
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.
What is highest common factor of 32 and 24?
To find the greatest common factor of two numbers, you first need to break them down into their prime factors. In this case, 32 and 24 can be split up as follows: 32 = 2x2x2x2x2 24 = 2x2x2x3 The next step is to identify the common factors. In this case, both numbers have three 2s as prime factors. Therefore, to find the HCF, you simply multiply these factors together: 2x2x2 = 8 Thus, 8 is the highest common factor of 32 and 24.
