What is the smallest positive multiple of 13 for which the sum of its digits is prime?
Start with the smallest multiple of 13 and continue with the next smallest until finding one that fits the specifications. 13, sum of digits is 1 + 3 = 4 which is not prime 26, sum of digits is 2 + 6 = 8 which is not prime 39, sum of digits is 3 + 9 = 12 which is not prime 52, sum of digits is 5 + 2 = 7 which is prime So, 52 is the smallest positive multiple of 13 for which the sum of its digits is prime.

Is it possible for a multiple of 13 greater then 13 to be a prime number?
It is not possible for any multiple of a prime number to be prime.
What number is relatively prime to 13?
Since 13 is a prime number (i.e., 13 is the only factor of 13), any number that is not a multiple of 13 is relatively prime to it.
Is 5629 prime?
5629 is a multiple of 13.
What is the least multiple of 13 only?
There is no least multiple because the sequence can go 13, 0 , -13 , -26, -39, -52 and so on without end. The least POSITIVE multiple is 13.
What is least common multiple of 9 and 13?
The Least Common Multiple (LCM) for 13 & 9 is 117.
What is the smallest positive multiple of 13 which is greater than 500?
39 *13 = 507
Why 143 is not a prime number?
A prime number is a positive integer that has exactly two positive integer factors. 1 and itself.11 x 13 =143 ,so 143 is not a prime number
What is the least common multiple of 13 and 40?

What is the least common multiple of 16 and 13?
The least common multiple of 13 and 16 is 208. Because 13 is prime, the LCM of 13 and 16 is their product. 13 * 16 = 208.
What is the least common multiple of 13 and 117?
Since 13 is a factor of 117, the least common multiple is 117. 13 x 9 = 117 117 x 1 = 117 Another way to determine the least common multiple is to multiply both numbers and divide by their greatest common factor. The greatest common factor of 13 and 117 is 13, so the least common multiple is 13 x 117 ÷ 13 = 117. Another way to determine the least common multiple is to determine the prime factors of the numbers and take the highest power of each prime factor. The prime factors of 13 are 13. The prime factors of 117 are 32 and 13. The highest power of 3 is 32 and the highest power of 13 is 131. Therefore, the least common multiple of 13 and 117 is 32 x 131 = 9 x 13 = 117.
