There are more composite numbers. The larger a number gets, the more likely it is to have multiple factors.
If a number is "on[l]y divisible by one and [a] prime number", as required by the question, then that number is prime. Therefore it cannot be composite.
Composite integers each have their own unique prime factorization. Since Y and W can be any number, we can't give a more specific answer.
74 is the on;y composite factor of 74.
When X and Y are prime numbers X + Y is even unless either X or Y = 2. (As 2 is the only even prime number)
The answer depends on Y.
The GCF of any two prime numbers is 1 and the LCM is their product.
suppose the n has the prime factorization of x*y. We know that every unique integer has a unique prime factorization. n*n = (x*y)*(x*y) = x^2*y^2.
First you express the numbers as their prime factors: 3y = 3, y y2 = y, y Next you identify any common prime factors. In this case both numbers have y as a prime factor. Finally you multiply the numbers and divide by the HCF: 3y(y2)/y = 3y2 and thus the LCM is 3y2
7 + 13 = 20 Note that there are no two prime numbers x and y that multiply to 20.

x+y=54 x-y=20 solving it,we get x=37 and y=17
