As 13 is prime and is not a factor of 24, then they are relatively prime
The only prime number (factor) of 169 is 13 (13 x 13 = 169).
To find the LCM of 26 and 42 you first need to break those numbers up into their prime factors. In this case, that would be: 26 = 2x13 42 = 2x3x7 The next step is to identify any common factors. In this case, both numbers have a 2 as a prime factor, so we can discard one of these. Take every other prime factor (2, 3, 7 and 13) and multiply them together to find the LCM: 2x3x7x13 = 546 Therefore the LCM of 26 and 42 is 546.
There is NO common factor between '13' & '19' , as both these numbers are prime numbers. However, they do have a common MULTIPLE which is 13 X 19 = 247.
13 and 19 are both prime numbers. Their only common factor is ' 1 '.
2 x 3 x 7 x 13 = 546
As 13 is prime and is not a factor of 24, then they are relatively prime
The only prime number (factor) of 169 is 13 (13 x 13 = 169).
The 3 factors of 169 are 1, 13, and 169. The factor pairs of 169 are 1 x 169 and 13 x 13.The prime factors of 169 are 13 and 13.The prime factorization of 169 is 13 x 13 or, in exponential form, 132.Factor Tree:One way to determine the prime factors is to construct a factor tree, continuing to factor each level until all the numbers have been factored into prime numbers. 16913 x 13Since 13 is a prime number, the factor tree is complete.13 x 13
1 17 and 13 are prime numbers

The prime factorization of 546 is:2 x 3 x 7 x 13546 is not a prime number2 x 3 x 91 = 546.
The PF of 546 is: 2 x 3 x 7 x 13
The 3 factors of 169 are 1, 13 and 169. The factor pairs of 169 are 1 x 169 and 13 x 13.The prime factors of 169 are 13 and 13.The prime factorization of 169 is 13 x 13 or, in exponential form, 132.Factor Tree:One way to determine the prime factors is to construct a factor tree, continuing to factor each level until all the numbers have been factored into prime numbers. 169 = 13 x 13Since 13 is a prime number, the factor tree is completeThey are: 13*13 = 1691, 13 and 169
'13' is a prime number, so there is no factor tree. However, to test , we can say 13)13 = 1 When reduced to '1' the factoring is complete. Prime numbers are 2,3,5,7,11,13,17,19,23,29.... This goes to infinity, however, the above list is primes to '30'.
There is NO common factor between '13' & '19' , as both these numbers are prime numbers. However, they do have a common MULTIPLE which is 13 X 19 = 247.
1,17&13, any prime numbers actually.
