No, there are composite numbers that end in every other digit.
All numbers that are greater than 5 and end in 5 are composite numbers because they are divisible by 5 in addition to 1 and the number itself. 655 is therefore a composite number.
No prime numbers end in 0. 130 is a composite.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)

23,465 is composite. All numbers greater than 5 that end in 5 are composite.
it is a composite number because the two at the end is even' and it has numbers that go into it
30 50 70 because they both end in 0 and 10 is a composite number

Composite, because it can be divided by '2'. NB All even numbers , except '2', are composite, therefore NOT prime. All prime numbers are odd number, except '2'. However, not all odd numbers are prime numbers. All EVEN numbers end in 0,2,4,6,8 All ODD numbers end in 1,3,5,7,9. Since '76' ends in '6' , then it is an even number, hence composite.
How about: 9, 39, 49, 69, 99 ..... etc which are all composite numbers because they have more than two factors
No prime numbers end in 0. 130 is a composite.
260 is a composite number, like all numbers greater than 1 that end in 0.
Not all composite numbers are even, but all even numbers except 2 are composite.
