The greatest common factor of 2 and 3 is 1. This is because 2 and 3 are prime numbers, that is, they only have themselves and one as factors. NOTE: Any time that one of the numbers is a prime number and the other is not a multiple of that Prime number, the greatest common factor is 1.
Another way to approach this, especially with larger numbers (but this makes a good example) is to look at the difference between 2 and 3, which is 1. 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. If the difference is 1, the greatest common factor is 1.

What is the greatest common factor 12 and 42?
The greatest common factor is 6 12= 2*2*3 42= 2*3*7 2*3= 6
What is the greatest common factor 60 and 84?
The GCF is 3.
What is the greatest common factor of 20 and 54?
The greatest common factor of 21 and 54 is 3. The greatest common factor is the highest number that divides exactly into two or more numbers. factors of 21: 1, 3, 7, 21 factors of 54: 1, 2, 3, 6, 9, 18, 27, 54 The greatest common factor of 21 and 54 is 3.
What is the greatest common factor of 48 and 6?
Since 6 is a factor of 48, and 6 is the largest factor of itself, 6 is the greatest common factor. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 6 are 1, 2, 3, and 6. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The common factors are 1, 2, 3, and 6. Therefore, 6 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 6 are 2 and 3. The prime factors of 48 are 2, 2, 2, 2, and 3. The common prime factors are 2 and 3, so the greatest common factor is 2 x 3 = 6.
What is the greatest common factor of 142 and 72?
72 is factored into: 2*2*2*3*3 142 factored into: 2*71 Their greatest common factor is just 2
What is the greatest common factor of 30 and 1224?
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 30 are 2, 3, and 5. The prime factors 1224 are 2, 2, 2, 3, 3, and 17. The prime factors in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.
What is the greatest common factor of 9and 16?
The greatest common factor of 9 (3 x 3) and 16 (2 x 2 x 2 x 2) is 1.
What is the prime factorization and the greatest common factor of 2456?
The prime factorization of 2456 is 2 x 2 x 2 x 307. There is not a greatest common factor. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Examples: The prime factorization of 36 is 2 x 2 x 3 x 3. The prime factors it has in common with 2456 are 2 and 2, so the greatest common factor is 2 x 2 = 4. The prime factorization of 921 is 3 x 307. The prime factors that it has in common with 2456 is 307, so the greatest common factor is 307.
What is the greatest common factor of 2 and 9?
Since 2 is a prime number, either it is the greatest common factor or 1 is. Since 2 is not a factor of 9, 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 2 are 1 and 2.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 2 is 2.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.Summary of results:The common factor is 1.The greatest common factor is 1.The numbers are relatively prime.The GCF is 1.The GCF is 1.
What is the greatest common factor 6 27?
1 is the greatest common factor of 8 and 27. It is also the least. It is also the only.
What is the greatest common factor of 18 and 75?
The greatest Common Factor (GCF) of 18 and 75 is 3.
What are the common factors and greatest common factor of 6?
There is neither a greatest common factor nor common factors of a single number, such as 6 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 6 are 1, 2, 3, and 6. The prime factors of 6 are 2 and 3. Examples: The common factors of 4 and 6 are 1 and 2; the greatest common factor is 2. The common factors of 6 and 9 are 1 and 3; the greatest common factor is 3. The common factors of 6 and 13 are a single 1; the greatest common factor is 1. The common factors of 6 and 24 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 6, 120, and 216 are 1, 2, 3, and 6; the greatest common factor is 6.
