Is the integer n a multiple of 15
Witryna24 mar 2024 · Let y be any integer. Express y = 5 q + r. Where r is the remainder of y after division by 5. And q is the quotient. Then, y 2 = y 2 = ( 5 q + r) 2 = 5 q 2 + 10 q r + r 2 = 5 ( q 2 + 2 q r) + r 2 = 5 k + r 2 If we want y 2 to be divisible by 5 then y 2 − 5 k = r 2 needs to be divisible by 5. WitrynaThe obvious solution is: int n = y; while (n < x) n *= y; return n == x Now I am thinking about how to improve it. Of course, I can check some special cases: e.g. both x and y should be either odd or even numbers, i.e. we can check the least significant bit of x and y. However I wonder if I can improve the core algorithm itself. algorithm math

Witryna7 gru 2024 · If n = 3, then the answer is NO but if n = 15, then the answer is YES. Not sufficient. From this statement though notice that n must be a multiple of 3, since n + 6 = 3 q --> n = 3 ( q − 2). (1)+ (2) From above we have that n is a multiple of both 5 and … Witryna18 lut 2024 · • The number n is a positive integer To find: • Whether n is a multiple of 20 or not Approach and Working: If we express 20 in terms of its prime factors, we get 20 = 2^2 x 5^1 • Therefore, if n is a multiple of 20, then n must have 2^2 and 5 as its factors. Analysing Statement 1 As per the information given in statement 1, n^3 is a multiple …
Witryna15 lut 2024 · St 1: n=4a where "a" is an integer. Now If n=4 then no but n=48 then yes. A and D are ruled out. St2: If n=6 then no if n=24 then yes. Combining we get n is muliple of 4 and 6 so n is a mulitple of 12 but need not be a multiple of 24...here's why. If n=12,36,60 then not a mutiple of 24, but. If n= 24,48 then Yes.

Note: You can use integers with mod to check if a number is a multiple We do not need loops. If the user inputs the number, only inputs multiples of 15, it will display "CS", "Computer" for multiples of 5 and "Science" for multiples of 3.
