A Prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself.
105 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 105 is a composite number.
113 is prime. 117 and 105 are composite.
3 x 5 x 7 is the prime factorization of 105.
105 is a composite number because it has factors other than 1 and itself. It is not a prime number. The prime factorization of 105 is 3 x 5 x 7.
It is prime
86 is not a prime number, so is a composite.
105 is a composite number
----It is Composite!It is composite because the number 5 goes into it!
105 is not prime. 105 = 3 * 5 * 7
105 is a composite number because it has more than 2 factors
105 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.
105 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.
105 cannot be the prime factorisation of anything since 105 is not prime.
1*105 3*35 5*21 7*15 Yes it is a composite number! A prime number has 2 factors, 1 and itself, and a composite number has 3 or more factors. The number 1 has only one factor and there fore is not prime and not composite.
Any number ending in a 5, other than the number 5 itself, is composite.
113 is prime. 117 and 105 are composite.
3 x 5 x 7 is the prime factorization of 105.
Because it has more than just 2 Prime Factors . 105 = 5 * 3 * 7.
