Well, isn't that a happy little mystery! If we look at the pattern, we can see that each number is decreasing by 13. So, if we continue that pattern, the missing number would be 26. Just a little bit of arithmetic magic to solve the puzzle!
13 X 3 = 39
The numbers which go into 39 are the factors of 39 which are: 1, 3, 13, 39. Any of its factors which are: 1, 3, 13 and 39
Something's missing from your question. There are 20 answers to your question. 39 + 0 = 39 38 + 1 = 39 37 + 2 = 39 . . . 19 + 20 = 39
To express the number 39 as a product of prime factors, we first identify that 39 is an odd number. We can start by dividing 39 by the smallest prime number, which is 2. Since 39 is not divisible by 2, we move on to the next prime number, which is 3. Dividing 39 by 3 gives us 13, which is a prime number. Therefore, the prime factorization of 39 is 3 x 13.
The greatest common factor is the highest number that divides exactly into two or more numbers. 13: 1, 13 39: 1, 3, 13, 39 The GCF for 13 and 39 is 13.
