17 has one factor pair, 1 and 17.
The factor numbers are 3 and -17.
The greatest common factor of the numbers 17, 68 and 34 is 17.
The greatest common factor of the numbers 17 and 34 is 17.
17 and 34 have a gcf of 17
1 17 and 13 are prime numbers
The GCF of 17 and 21 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 17 are 1 and 17.The factors of 21 are 1, 3, 7, and 21.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.1 because 17 is a prime number
1, 7, 17, 119
The greatest common factor of the numbers 323 and 391 is 17.
The GCF of 11 and 17 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 11 are 1 and 11.The factors of 17 are 1 and 17.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor (GCF) is 1.The GCF is 1.
For this kind of question, I would suggest looking up a table of prime numbers. As an alternative, you can try to find factors for each of the numbers - if it has a factor, it is NOT a prime. For this range of numbers, testing for prime numbers up to 13 is appropriate. (If 17 is a factor of one of these numbers, the other factor is less than 17, so you would already have found it before you reach 17.)
323 17 x 19 Both 17 and 19 are prime numbers, so the factor tree is finished.
