Two multiples of any number greater than one can't be co-prime. They would always have that number as a common factor.
Multiples of 13, like 13, 26 and 39.
Multiples of 13 have 13 as a factor. 13, 26, 39 and so on.
The prime numbers: 2, 3, 5, 7, 11, 13, 17, 19
'26' has only two factors, they are '2' & '13' ; 2 x 13 = 26 or 13 x 2 = 26 Both '2' and '13' are prime numbers.
In that range... 2, 3, 5, 7, 11 are prime. 1, 3, 5, 7, 9, 11 are odd. 1, 4, 9 are square. 3, 6, 9, 12 are multiples of 3. 0, 2, 4, 6, 8, 10, 12 are even.
No multiples of the same number greater than one can be co-prime, since they will both have that number as a factor.
It can be. Since 13 is a prime number, it is relatively prime to all other numbers except for multiples of 13.
Since both 11 and 13 are prime numbers, the LCM of these 2 number is 11 * 13 = 143. All multiples of 143 are multiples of 11 and 13 as well
Themselves and their multiples because 17 and 13 are both prime numbers.
The prime numbers between 13 and 28 are 13 17 19 23 Multiples of 7 in that range include 14, 21 and 28.
The LCM of the given prime numbers is 39
There are two prime numbers that equals 50. The two numbers are 13 & 37. Both numbers are prime, so that's the answer.
If they have a Prime multiple in common, then they are not co-prime numbers.Hence no 2 multiples of 13 exists to satisfy this condition.
13*31=403 13 and 31 are prime numbers.
39 is the product when the two prime numbers 3 and 13 are multiplied.
None. Prime numbers only have two factors.
The two proper prime factors are 7 and 13.
