Can you arrange the numbers 1 through 15 in the hexagonal cells shown below


so that the sum of the numbers along each side of the triangle is the same AND so that the product of the numbers at the vertices (pink cells) equals the product of the numbers in the middle (green cells) ? Hint: The sum of the numbers in the center and the sum of the numbers at the vertices have to be equivalent modulo 3.
