Since 13 is a factor of 39, all of its factors are common.
1 and 13 are their only common factors.39: 1, 3, 13, 3965: 1, 5, 13, 65
To find the GCF of 13 and 39, you can list the factors of each number. The factors of 13 are 1, 13. The factors of 39 are 1, 3, 13, 39. 13 is the GCF of 13 and 39. 3 is a prime number has only two factors: 1 and 13. 13 will divide into 39 three times. Since 13 is a prime number that will divide into 39, it has to be the GCF of 13 and 39.
The common factors of 26 and 39 are the numbers that can evenly divide both 26 and 39 without leaving a remainder. The factors of 26 are 1, 2, 13, and 26. The factors of 39 are 1, 3, 13, and 39. The only common factor of 26 and 39 is 1.
4u2 - 6u - 39 does not have rational factors.
Not all of them because 39 is an odd number that is not a prime number because it has more than two factors whereas prime numbers have only two factors.
No because as for example 39 is an odd number but it is also a composite number because it has more than two factors and prime numbers have only two factors.
39 is an odd number. Only numbers that end with 0, 2, 4, 6 and 8 are even.
39 is an odd number
No. 39 is odd but 6 is even and all multiples of 6 are even.
Since 13 is a factor of 39, all of its factors are common.
The factors of 39 are: 1, 3, 13, 39.
1, 3, 13, 39.
1, 3, 13, 39
Yes. Composite numbers have more than exactly two factors; 39 has four factors: 1, 3, 13, 39. Prime numbers have exactly two factors, eg 3 has the two factors 1 and 3. Square numbers have an odd number of factors, eg 36 has nine factors: 1, 2, 3, 4, 6, 9, 12, 18, 36. The number 1 is not prime as it only has one factor: 1.
6 is even. 33 is odd. 33+6=39. 39 is odd.
