What is the greatest common factor of 20 and 55?

One way to determine the 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 55 are 1, 5, 11, and 55. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors in common are a single 5, so the greatest common factor is 5.


What is the greatest common factor of 20 12 and 20?

The GCF of 12 and 20 is 4.The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors they have in common are 1, 2, and 4. Therefore, 4 is the greatest common factor.The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The common prime factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.The greatest common factor of 12 and 20 is 4


Which number does not belong 20 - 14 - 6 - 19?

Whichever one you want: 20: It is the only number with a repeated prime factor. 14: It is the only number with two non-adjacent prime factors. 6: It is the only number with two adjacent prime factors. 19: It is the only prime number. So now you need to second-guess the person who asked the question!


What is the common factor of 16 and 20?

The factors of 16 are 1, 2, 4, 8, and 16. The factors of 20 are 1, 2, 4, 5, 10, and 20. The largest of the factors they have in common is 4, so 4 is the greatest common factor. Using prime factorization: The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 20 are 2, 2, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.


What is the greatest common factor of 20 55 and 85?

The GCF of 20, 55, and 85 is 5 One way to determine the 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 55 are 1, 5, 11, and 55. The factors of 85 are 1, 5, 17, and 85. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors of 85 are 5 and 17. The prime factors in common are a single 5, so the greatest common factor is 5.

The prime factors of 20 are 2 and 5.


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.
