[#R683] The interval 30,922 to 30,929 has a six-color square-prime certificate

claim. Exact factorizations prove both endpoints squarefree and label the six interior integers by 17, 3, 5, 47, 13, and 2.

1Summary

The endpoint factorizations are \[ 30922=2\cdot15461, \qquad 30929=157\cdot197, \] and every displayed factor is prime. Thus both endpoints are squarefree.

The interior factorizations are \[ \begin{aligned} 30923&=17^2\cdot107,\\ 30924&=2^2\cdot3^2\cdot859,\\ 30925&=5^2\cdot1237,\\ 30926&=2\cdot7\cdot47^2,\\ 30927&=3\cdot13^2\cdot61,\\ 30928&=2^4\cdot1933. \end{aligned} \] Assigning the primes \[ (17,3,5,47,13,2) \] in increasing order of the interior integers gives six distinct labels, each with its square dividing the corresponding integer.
