Except for 2, all other prime numbers are odd. The sum of any two odd numbers is even. Therefore, the Prime number 2 will evenly divide the sum of any other two prime numbers.
Here are some examples to illustrate this:
3 + 5 = 8 which is evenly divisible by 2
13 + 19 = 32 which is evenly divisible by 2
43 + 47 = 90 which is evenly divisible by 2

What is the greatest common factor of 28 and 140 and 175?
1 no other number divides into all of them evenly
What number goes into 77 evenly?
The numbers 7 and 11 divide into 77 evenly. We know that 7 x 11 = 77, and as 7 and 11 are both prime numbers, there are no other numbers that go into 77 evenly.
What is the gcf of 3 and 5 and 8?
The greatest common factor, or GCF, of any numbers is the largest number that divides evenly into all of the numbers. Here, that would be 1 because both 3 and 5 are prime, and they share no common factors with each other nor 8.
What do you call a number that cannot be divided evenly by any numbers other than itself and one?
A prime number
Is the GCF of two numbers equal to the lesser of the numbers?
Oh honey, no. The Greatest Common Factor (GCF) of two numbers is the largest number that divides both of them evenly. It's not just the lesser of the two numbers, it's the biggest number that can play nice with both of them. So, don't sell the GCF short, it's got a big job to do.
When are two numbers factors of a product number?
When one of them divides evenly into the product with no remainder and the result is the other number.
What is the great common factor of 24 and 32?
The greatest common factor, or GCF of a number is the largest positive integer that divides evenly into all of the other integers. Here, that would be 8.The greatest common factor, or GCF, is the largest number that divides evenly into all the other numbers. Here, with 24 and 32, the GCF is 8 because that is the largest number that divides evenly into both.
What is the greatest common factor of 32 80 50?
The GCF of all those is the largest number that divides evenly into all of them. Here, the GCF is 2 because no other numbers evenly divide into all of the above numbers.
What number goes into the numbers 3 4 5 evenly?
As 3 and 5 are Prime numbers, no other number will go evenly into them. (presuming that "evenly" means a multiple of two). If you are looking for a common factor of 3, 4, and 5, then the answer is 1.
What number divides evenly into 53?
1 and 53. The number 53 is a prime number.
What are the prime numbers that seven goes into -1000?
The only prime number that 7 will evenly divide is 7. Any other number that 7 evenly divides will not be prime because it will have more than the exactly two factors (1 and itself) that prime numbers have, since 7 will be also be a factor.
What number divides into 151 equally?
151 is a prime number, which means it can only be divided evenly by 1 and itself. Therefore, there is no other number that divides into 151 equally.
How is the number 1 unique when compared to other numbers?
It is a Composite Number when it can be divided evenly by numbers other than 1 or itself.It is a Prime Number when it can't be divided evenly by any number (except 1 or itself).
What is the greatest common factor of 28 and 140 and 175?
1 no other number divides into all of them evenly
Is 1589 composite or prime?
its composite, it divides evenly by 7, 1, and likely some other larger numbers as well, prime numbers are only divisable by 1
What number goes into 77 evenly?
The numbers 7 and 11 divide into 77 evenly. We know that 7 x 11 = 77, and as 7 and 11 are both prime numbers, there are no other numbers that go into 77 evenly.
What number goes into 77 and 100?
The number that goes into both 77 and 100 is 1. This is because 1 is a factor of every integer, meaning it divides evenly into both 77 and 100 without leaving a remainder. In contrast, other numbers such as 2, 3, 4, etc. do not divide evenly into both 77 and 100.
