Why composite number are not used in rsa algorithm?
If you choose any two numbers, the RSA encryption and decryption is still correct. However, not all numbers of a given length are equally hard to factor. The hardest instances of these problems (for currently known techniques) are semiprimes, the product of two prime numbers. For example, factoring 35 (= 5 * 7) is difficult than 36 (= 4 * 9 or 6 * 6).
What are the composite numbers between 20 and 70?
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.
What are the composite numbers in 1-60?
The numbers 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 are composite.
Are two composite numbers always sometimes or never true?
They are always true - if your calculations are sound.
Is the number 42 prime or composite what are the factors?
42 is a composite number because it has at least one positive factor other than one or itself.
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.
How do you write a composite number as a product of two prime numbers?
To write a composite number as a product of two prime numbers, write it as an answered multiplication question like 2 x 17 = 34 or 3 x 3 x 7 = 63.
Is the number 41 a composite number?
No because it has only 2 factors which are itself and one therefore 41 is a prime number
What are 2 composite numbers with the GCF of 1?
I take it you are asking for an example, not a definition. Okay. Here are 2: 4 and 9.
What are the 25 first composite numbers?
Here are the first 105: 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.
Can 6 prime numbers be added and get a composite number?
Yes.
The sum of any six prime numbers, excluding 2, will be even. So the sum will be composite.
What are three consecutive composite numbers whose product is 192?
They are: 4*6*8 = 192 because 5 and 7 are prime numbes
