Multiples of 1260 are all integers divisible by 1260 , i.e. the remainder of the full division by 1260 is zero. There are infinite multiples of 1260. The smallest multiples of 1260 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1260 since 0 × 1260 = 0
1260 : in fact, 1260 is a multiple of itself, since 1260 is divisible by 1260 (it was 1260 / 1260 = 1, so the rest of this division is zero)
2520: in fact, 2520 = 1260 × 2
3780: in fact, 3780 = 1260 × 3
5040: in fact, 5040 = 1260 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1260, the answer is: No, 1260 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 1260). 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 35.496 ). 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.
