To find the GCF of two or more numbers, you can list the factors of each of the numbers and find one that is common to all the numbers.
Factors of 2 are 1 and 2
Factors of 3 are 1 and 3
Factors of 4 are 1, 2, and 4
Factors of 8 are 1, 2, 4, and 8
Besides 1, the numbers 2, 4, and 8 have 2 as a common factor. They have no factors other than 1 in common with 3.

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 of 18 and 75?
The greatest Common Factor (GCF) of 18 and 75 is 3.
What is the greatest common factor of 24 and 48?
24 is a factor of 48, and 24 is the largest possible factor of itself, so 24 is the greatest common factor.The GCF or Greatest Common Factor would be 24.24 = (2)(2)(2)(3)48 = (2)(2)(2)(3)(2)(2)(2)(2)(3) = 24
What is the greatest common factor of 9 and 12?
The greatest common factor of 9 and 12 is 3. 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 12 are 1, 2, 3, 4, 6, and 12. The common factors are 1 and 3. Therefore, the greatest common factor is 3. 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 12 are 2, 2, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.
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.
