Multiples of 160 are all integers divisible by 160 , i.e. the remainder of the full division by 160 is zero. There are infinite multiples of 160. The smallest multiples of 160 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 160 since 0 × 160 = 0
160 : in fact, 160 is a multiple of itself, since 160 is divisible by 160 (it was 160 / 160 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 160, the answer is: No, 160 is not a prime number.
To know the primality of an integer, we can use several algorithms. The most naive is to try all divisors below the number you want to know if it is prime (in our case 160). We can already eliminate even numbers bigger than 2 (then 4 , 6 , 8 ...). Besides, we can stop at the square root of the number in question (here 12.649 ). Historically, the Eratosthenes screen (which dates back to Antiquity) uses this technique relatively effectively.
More modern techniques include the Atkin screen, probabilistic tests, or the cyclotomic test.
