Anything that is not 1, 2, 3, 6, 9, and 18.

1 + 2 = 3 which is a factor of 96 (32*3 = 96)

The least common factor of any set of numbers is 1.

The factors of the numbers are 12: 1, 2, 3, 4, 6, and 12 15: 1, 3, 5, and 15 30: 1, 2, 3, 5, 6, 10, 15, and 30 The GCF of the three numbers is the largest number that is a factor of all three numbers, which is 3.

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.

The only number that is a factor of all the numbers from 1 to 100 is the number 1. The only factor of 1 is 1. The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The factors of 5 are 1 and 5. The factors of 6 are 1, 2, 3, and 6. The factors of 7 are 1 and 7. The factors of 8 are 1, 2, 4, and 8. The factors of 9 are 1, 3, and 9. The factors of 10 are 1, 2, 5, and 10. The only common factor of these ten numbers is 1. Since all numbers are divisible by 1, the greatest common factor is 1.

1 1*2=2 1*3=3 2 and 3 are both prime numbers, so they are only divisible by 1 and themselves.

The greatest common factor of several numbers cannot be larger than the greatest common factor of any pair of the numbers. If you realize that the greatest common factor of 3 and 5 is 1, the greatest common factor of all the numbers must be 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8. The factors of 10 are 1, 2, 5, and 10. 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 3 is 3. The prime factor of 5 is 5. The prime factors of 8 are 2, 2, and 2. The prime factors of 10 are 2 and 5. There are no prime factors in common, so the greatest common factor is 1.

The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The only common factor is 1. Therefore, the least (smallest) common factor is 1. If you mean LCM then it would be 6

They are: 1 2 3 6 9 and 18

The GCF of 2, 3, and 6 is 1. The numbers are relatively prime.

The greatest common factor is a factor that two or more numbers have in common. When there are three numbers, it must be a factor that all three numbers have. Examples: What is the greatest common factor of 6, 9, and 21? The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The factors that all three numbers have in common are 1 and 3, so the greatest common factor is 3. What is the greatest common factor of 3, 7, and 15? The factors of 3 are 1 and 3. The factors of 7 are 1 and 7. The factors of 15 are 1, 3, 5, and 15. There is only one factor that all three numbers have in common - 1. Therefore, the greatest common factor is 1. What is the greatest common factor of 12, 96, and 108? The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96. The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108. The factors that all three numbers have in common are 1, 2, 3, 4, 6, and 12, so the greatest common factor is 12. The same as with two. Example: 30, 42 and 66. Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 3 x 11 = 66 Select the common factors. 2 x 3 = 6, the GCF
