What are the multiples of 780?
Multiples of 780 are all integers divisible by 780 , i.e. the remainder of the full division by 780 is zero. There are infinite multiples of 780. The smallest multiples of 780 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 780 since 0 × 780 = 0
780 : in fact, 780 is a multiple of itself, since 780 is divisible by 780 (it was 780 / 780 = 1, so the rest of this division is zero)
etc.
Is 780 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 780, the answer is: No, 780 is not a prime number.
How do you determine if a number is prime?
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 780). 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 27.928 ). 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.
