Yes.
Yes as both divisible by 3 so 15/426 = 5/142
No, it is clearly a multiple of 2, making it not a prime number.
2 x 3 x 71 = 426
14.2
71 times 3 =426
No. 426 is only divisible by: 1, 2, 3, 6, 71, 142, 213, 426.
No. But it is divisible by: 1 2 3 6 71 142 213 and 426.
Yes as both divisible by 3 so 15/426 = 5/142
Yes. 426/6 = 71
No, it is clearly a multiple of 2, making it not a prime number.
1, 2, 3, 6, 9, 18, 71, 142, 213, 426, 639, 1278
it is but it comes out 106.5 which is uneven so probably not
426-3 = 423
3,408 is divisible by 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, 71, 142, 213, 284, 426, 568, 852, 1136, 1704, 3408.
It is because 186426 = 3*62142 and 186426 = 9*20714.
142, 284, 426 and keep adding 142 forever.
