No, just 1 and 7.
All prime numbers like 7 only have two factors 1 and itself.
28 7, 4, 2
The number 21 has only four factors: 1, 3, 7, and 21. Many number have more than four factors. Among them are 1x2x3x4x5 = 120.
21 is a Composite Number. A prime number is a whole number that only has two factors which are itself and one. A composite number has factors in addition to one and itself. 21 is divisible by 3 and 7.
3, 7, and 19 have only two factors, 1 and itself. They are prime numbers. 21 has more than 2 factors: 1, 3, 7, and 21. It is a composite number.
A composite number is any number who has more than 2 factors. ex: 10 Factors of 10 = 1, 2, 5, 10. 10 has 4 factors, and is composite. ex: 7 Factors of 7 = 1, 7. 7 has 2 factors, and is not composite. Anything with 2 factors is called Prime. it has factors of 1 and itself only. To find the factors of 208, see if you can divide it by a number evenly. 2 will work, since 208 is even. This means, so far the factors are 1, 2 and 208. (there are more) But I will stop here, because 208 has at least 3 factors. 3 is more than 2, and when a number has more than 2 factors.... 208 is composite.
Yes. 7 is more than 3.
2 x 7 x 135 more than 9 is 1419 less than 22 is 3Prime factors of the product of 3 and 14 are 2, 3, and 7.
6Improved answer:The prime factors of 84 are 2, 3 and 7: 2*2*3*7 = 846 is not a prime number because it has more than two factors.
Even numbers do not necessarily have more factors than odd numbers. For example, the number 6 has 4 factors, 1, 2, 3 and 6. However, the number 63 has 1, 3, 7, 9, 21, 63 as its factors. We can see that 63 has more factors than 6. On the other hand, 3 has just 2 factors, 1 and 3. This means that the whether a number has many factors is not related to if it is odd or even.
10 is 7 more than 3
A composite number is a number that has more than two factors. The factors of 21 are 1, 3, 7, and 21. Therefore, 21 is a composite number.
The prime factors of 21 are 3 and 7 The prime factors of 35 are 5 and 7 The prime factors of 56 are 2, 2, 2, and 7 As 56 has more than two prime factors it therefore has other factors which are not prime... 4, 8, 14 and 28.
