13 is a prime number in that range. So are 11, 17 and 19.
No. As soon as you see that '0' at the end, you know it's a multiple of '10'.No multiple of '10' can be a prime, because in addition to itself and '1', it alsohas '2' and '5' for factors.In addition to '2' and '5', this particular number also has factors of4, 7, 8, 10, 14, 16, 20, 28, 32, 35, 40, 56, 70, 80, 112, 140, 160, 224, 280, and 560.It misses being a prime number by just a wee bit.
Among the whole numbers alone, 10 is a multiple of 1, 2, 5, and 10. It's also a multiple of an infinite number of fractions and decimals.
No it isn't, it's divisible by 10 and 2 and 5. Also, No 780 is not a prime number. A prime number is defined as a number whos divisbility is 1 and its self.
No, it is an even number greater than 2 and is also divisible by 10. It is a composite number.
It is a multiple of 2, and so is composite.
13 is a prime number in that range. So are 11, 17 and 19.
The prime number less than 10 that, when added to either 10 or 20, results in a prime number is 3. When you add 10 to 3, you get 13, which is a prime number. Similarly, when you add 20 to 3, you get 23, which is also a prime number.
No, a prime number is a number that can only be divided by 1 and itself. 10 can also be divided by 2 and 5.
Since the number 10 has the prime factorization of 2 x 5, any multiple of 10 has the numbers 2 and 5 in their prime factorization.
73 is a prime number but 70 is not. 70 is a multiple of: 2, 5, 7, 10, 14 and 35 (as well as 1 and 70); the prime factorization of 70 is 2 × 5 × 7.
25 is a composite number. The prime factorization of 25 is 5 x 5. 2 x 5 is the prime factorization of 10.
111 + 1 = 2
Neither 4 nor 10 is prime. A prime number is a number that is evenly divisibly only by 1 and itself, not any other numbers. 4 is also divisible by 2. 10 is also divisible by 2 and 5. Therefore, both 4 and 10 are composite numbers.
