Multiples of 948 are all integers divisible by 948 , i.e. the remainder of the full division by 948 is zero. There are infinite multiples of 948. The smallest multiples of 948 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 948 since 0 × 948 = 0
948 : in fact, 948 is a multiple of itself, since 948 is divisible by 948 (it was 948 / 948 = 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 948, the answer is: No, 948 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 948). 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 30.79 ). 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.
