What are the common factors and greatest common factor of 20?
There is neither a greatest common factor nor common factors of a single number, such as 20, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.
What is the greatest common factor of 9 and 20?
The GCF of 9 and 20 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 20 are 1, 2, 4, 5, 10, and 20. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 9 are 3 and 3. The prime factors of 20 are 2, 2, and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1. Another way to approach this is to look at the difference between 9 and 20, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since 11 is a prime number, the greatest common factor must be either 1 or 11. The numbers 9 and 20 are not divisible by 11, so the greatest common factor must be 1.
What is a factor multipacation?
A factor is the two numbers you multiply for example: 20x20=400 Both 20 and 20 are factors. The 400 is a product.
What numbers are multiples 5 and factors of 20?
5, 10, and 20 are all multiples of 5 and factors of 20.
What two digit number is a factor of 20?
Both 10 and 20 are two-digit numbers that are factors of 20.
How are 125410 and 20 factors of 20?
20 is a factor of 20, 125,410 is not. If you mean 1,2,4,5,10 and 20, those are the only whole numbers that will divide into 20 evenly. They are known as factors.
What are the common factors that 20 and 27 have without any of them going in to both numbers?
Common factors have to go into both numbers. The only common factor of 20 and 27 is 1.
Which numbers have 2 and 4 as factors?
Every multiple of 4 has 2 and 4 as factors.
What is the greatest common factor of 14 15 and 20?
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 14 are 1, 2, 7, and 14. The factors of 15 are 1, 3, 5, and 15. The factors of 20 are 1, 2, 4, 5, 10, and 20. The only common factor is 1. Therefore, the greatest common factor is 1.
You selecting a number from the numbers 1-20. What is the probability the number you select is a factor of 20?
30% chance. First, find the factors of 20: {1,2,4,5,10,20} There are 6 factors, out of 20 possible numbers. 6/20 = .3 = 30%
What is the greatest common factor of 20 40 and 60?
Answer: 20Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.The common factors are 1, 2, 4, 5, 10, and 20. Therefore, the greatest common factor is 20.
