10, 25, 50
25 is, 1 x 25 and 5 x 5 which makes 25 a composite number not a prime.
no 5 is not a composite number 10 15 20 and 25 are composite
A composite number is a positive integer which has a positive divisor other than one or itself. In other words, if n > 0 is an integer and there are integers 1 < a, b < n such that n = a × b, then n is composite. By definition, every integer greater than one is either a prime number or a composite number. The number one is a unit - it is neither prime nor composite. For example, the integer 14 is a composite number because it can be factored as 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.The first 105 composite numbers are:4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140.
25 is a composite number because it has more than two factors
A composite number is a number that has at least 3 factors. (It can be evenly divided by at least 3 number.) 25 has 3 factors: 1, 5, and 25.
It is 25 because as a composite number it has more than two factors
Composite because it has more than two factors.
A prime number has no factors other than 1 and itself. 25 is a composite number because its factors are 1, 5, and 25.
A composite number is a number that is not a prime number, ie it has more than two distinct factors. The factors of 25 are 1, 5, 25 - three distinct factors.
125 is a composite number because it has more factors than 1 and itself. The factors of 125 are 1, 5, 25, and 125.
A composite number has 3 or more factors. Example: 10 is a composite number because it has 4 factors: 1, 2, 5 and 4. You find these using multiplication or division. Another example is 25. It has 3 factors which are 1, 5 and 25.
composite because it has more than two factors
15, 25, 75 are the composite factors of 75.
125 is a composite number because it has more than two factors. Its factors are 1, 5, 25, and 125.125 is divisible by 5 in addition to 1 and itself. It is a composite number.125 is a composite number. In addition to 1 and itself, it is divisible by 5.
25 and 27 are composite numbers because they both have factors in addition to 1 and themselves.
