Just the number 1.
The GCF of 18, 17, and 15 is 1 because 17 is a prime and has no factorsx other than 1 and 17, and 17 is not a factor of 18 or 15. Detailed work: Factors of 18: 1 2 3 6 9 18 Factors of : 1 17 Factors of : 1 3 5 15 The GCF of 18, 17, and 15 is 1
The factors of 17 are: 1, 17 The factors of 187 are: 1, 11, 17, 187 The common factors are: 1, 17
The factors of 17 are 1 and 17. For them to be common, they need to be compared to another set of factors.
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 both numbers have in common.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 17 are 1 and 17The only common factor is 1. Therefore, the greatest common factor is 1.
There are no common factors of 15 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 15 are 1, 3, 5, and 15.Examples:The common factors of 6 and 15 are 1 and 3.The common factors of 15 and 90 are 1, 3, 5, and 15.1,5,3, and 15.
17 is prime so its factors are 1 and 17. 17 is neither a factor of 15 nor 30, so the GCF is 1.
Common factors of 17 and 50 are: 1.
The factors of 17 are: 1, 17 The factors of 23 are: 1, 23 The common factors are: 1 The Greatest Common Factor: 1
The factors of 51 are 1, 3, 17, and 51. The factors of 119 are 1, 7, 17, and 119. The factors they have in common are 1 and 17. Therefore the greatest common factor is 17. The greatest common factor can also be determined from the prime factors. The prime factors of 51 are 3 and 17. The prime factors of 119 are 7 and 17. The prime factors they have in common are a single 17, so the greatest common factor is 17.
The factors of 119 are: 1, 7, 17, 119 The factors of 323 are: 1, 17, 19, 323 The common factors are: 1, 17
The factors of 17 are: 1, 17 The factors of 20 are: 1, 2, 4, 5, 10, 20 The common factors are: 1 The Greatest Common Factor: 1
Since 15 is a factor of 45, its factors are the common factors of 15 and 45. The factors of 15 are 1, 3, 5, and 15. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors they have in common are 1, 3, 5, and 15.
