Multiples of 762 are all integers divisible by 762 , i.e. the remainder of the full division by 762 is zero. There are infinite multiples of 762. The smallest multiples of 762 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 762 since 0 × 762 = 0
762 : in fact, 762 is a multiple of itself, since 762 is divisible by 762 (it was 762 / 762 = 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 762, the answer is: No, 762 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 762). 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 27.604 ). 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.
