-- It ends in a 5, so 5 is a factor of it.
-- The sum of its digits (15) is divisible by 3, so 3 is a factor of it.
It probably has tons of other factors, but either of these is enough
to prove that it's composite.
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
The number 1 is neither prime nor composite.
They are: 12343+2 = 12345
neither prime or composite
It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
Why is 1 neither prime nor composite
Make a circle, put all the numbers including prime and composite numbers. Then everything outside that circle is your answer.
composite; it is divisible by 1,2,3,4,6,8,12,16,24,32,48, and 96
29 is a prime number - it has no other factors apart from itself and 1.
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
50 is a composite number because it has more than two factors
45 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
A positive integer greater than one must be either prime or composite. It cannot be neither. 2 divides 160. That is, 160 has a factor other than 1 and itself. So it is not a prime and therefore is composite.
1 is neither. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
11x3 compositea composite number.............
The number 1 is neither prime nor composite.
30 is a composite number because it has more than two factors whereas a prime number has only two factors
