Determine GCF:
126 = 2 · 32 · 7
90 = 2 · 32 · 5
GCF: 2 · 32, or 18
The board is 7 x 5 squares.

Prime factorization of 126 = 2 * 3 * 3 * 7
Prime factorization of 90 = 2 * 3 * 3 * 5
Longest possible length = GCF = 2 * 3 * 3 = 18
Prime factorization of 90 = 2 * 3 * 3 * 5
Longest possible length = GCF = 2 * 3 * 3 = 18
