Yes except for 2 on its own which is the only even prime number.
Is it true or false that all numbers with a 0 in the ones' place are composite numbers?
It is true (as long as there are no decimal places after the ones place) because those numbers will always be divisible by 2, 5, and 10. With exception of the number zero which is neither prime nor composite.
Is 185 composite or prime?
185 is composite because anything that has 5 in the ones place is always divisible by 5. A prime number is a number that can only divided equally by itself and 1, so since 185 is divisible by 185, 1, 5, and 37, it is not a prime number.
Is 189 a prime or composite number?
189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.
Why is every natural number with a zero in the ones place composite?
Since the 0 is in the ones place, it will make the whole number even. An even number is composite because it can be divisible by 2 and other numbers too.
Why every natural number with a 0 in the ones place is a composite number?
They're all multiples of 10.
Is 605 a prime number or a composite number?

Which of the folling is a composite number?
The ones with more than two factors.
Are all numbers with a 0 in the ones place a composite numbers?
Yes. All numbers with 0 in the one's column are composite, having at least the factors of 1, 2, 5, and itself. The number 0 is also composite, having all numbers as factors.
