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
426-3 = 423
it is but it comes out 106.5 which is uneven so probably not
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.
