1-71.

Aruni found an incomplete multiplication puzzle. Help him fill in the empty boxes.

Remember that the numbers in the white boxes are the product of two numbers on the outside edges. This means $35$ is the product of $7$ and what other number?

Begin by completing the parts you are sure about and then look for patterns to help you complete the rest.
