How about: 31+7 = 38
The prime factors of the number 38 are 2 and 19.
38
37 +1
There is only one number that equals 38. That number is . . . . . 38.
38
1 x 38, 2 x 19 = 38
Composite, even numbers are divisible by two
38 is not a prime number. It can be factored as 2 x 19.
19 and 19, 38 and 20
No because they are composite numbers with more than two factors
To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
Let's fix the question. What are the prime factors of 38? 38 = 2 x 19 the prime factors of 38 are 2 and 19.
