Best Answer

Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 23, 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.

Examples:

The common factors of 23 and 25 are only 1; the greatest common factor is 1.

The common factors of 23 and 69 are 1 and 23; the greatest common factor is 23.

The common factors of 23 and 75 are only 1; the greatest common factor is 1.

The factors of 23 are 1 and 23. For them to be common, they need to be compared to another set of factors.

The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 138 are 2, 3, and 23. The prime factors of 322 are 2, 7, and 23. The prime factors in common are 2 and 23, so the greatest common factor is 2 x 23 = 46.

Because both numbers are prime numbers, the only common factor they have is 1. Therefore, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 5 are 1 and 5. The factors of 23 are 1 and 23. 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 factor of 5 is 5. The prime factor of 23 is 23. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

There is not a greatest common factor of a single number, such as 69, because there cannot be a greatest 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. The factors of 69 are 1, 3, 23, and 69. The prime factors of 69 are 3 and 23. The prime factorization of 69 is 3 x 23. Examples: The greatest common factor of 51 and 69 is 3. The greatest common factor of 32 and 69 is 1. The greatest common factor of 69 and 115 is 23. You need at least two numbers to find a GCF. If that's 6 and 9, the GCF is 3.

The factors of 184 are: 1, 2, 4, 8, 23, 46, 92, 184 The factors of 207 are: 1, 3, 9, 23, 69, 207 The common factors are: 1, 23 The Greatest Common Factor: GCF = 23

There is neither a greatest common factor nor common factors of a single number, such as 25, 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 25 are 1, 5, and 25.Examples:The common factors of 13 and 25 are only 1; the greatest common factor is 1.The common factors of 23 and 25 are only 1; the greatest common factor is 1.The common factors of 25 and 30 are 1 and 5; the greatest common factor is 5.The common factors of 25 and 42 are only 1; the greatest common factor is 1.The common factors of 25 and 50 are 1, 5, and 25; the greatest common factor is 25.

The Greatest Common Factor (GCF) is: 1

1 and 23 1 and 29 The only and therefore greatest common factor of 23 and 29 is 1.

Since 23 is a prime number, its only factors are 1 and itself. Since 42 is not divisible by 23, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 23 are 1 and 23. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. 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 factor of 23 is 23. The prime factors of 42 are 2, 3, and 7. There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.

The GCF of 4 and 23 is 1Definition: 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 4 are 1, 2, and 4.The factors of 23 are 1 and 23.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.

17 and 23 are both prime. The only factors they have are one and themselves. Their only factor in common is 1 so it has to be the greatest common factor.

1, they have no common factors except 1

Both 23 and 29 are prime; their only factors are 1 and themselves. Therefore, the greatest common factor is 1.

The numbers are primes so their only common factor is 1, and that means the greatest common factor is 1.
