0 : in fact, 0 is divisible by any integer, so it is also a multiple of 700001 since 0 × 700001 = 0
700001 : in fact, 700001 is a multiple of itself, since 700001 is divisible by 700001 (it was 700001 / 700001 = 1, so the rest of this division is zero)
1400002: in fact, 1400002 = 700001 × 2
2100003: in fact, 2100003 = 700001 × 3
2800004: in fact, 2800004 = 700001 × 4
3500005: in fact, 3500005 = 700001 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 700001, the answer is: yes, 700001 is a prime number because it only has two different divisors: 1 and itself (700001).
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 700001). 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 836.661 ). 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.
