No. But it is divisible by: 1 2 3 6 71 142 213 and 426.
Yes.
1, 2, 3, 6, 9, 18, 71, 142, 213, 426, 639, 1278
Yes as both divisible by 3 so 15/426 = 5/142
Yes because 6*71 = 426
71
0.0141
it is but it comes out 106.5 which is uneven so probably not
6 goes into 426 71 times.
142, 284, 426 and keep adding 142 forever.
The GCF is 6.
