Evaluate

$$3628800$$

Solution Steps

Multiply 1 and 2 to get 2.

$$2\times 3\times 4\times 5\times 6\times 7\times 8\times 9\times 10$$

Multiply 2 and 3 to get 6.

$$6\times 4\times 5\times 6\times 7\times 8\times 9\times 10$$

Multiply 6 and 4 to get 24.

$$24\times 5\times 6\times 7\times 8\times 9\times 10$$

Multiply 24 and 5 to get 120.

$$120\times 6\times 7\times 8\times 9\times 10$$

Multiply 120 and 6 to get 720.

$$720\times 7\times 8\times 9\times 10$$

Multiply 720 and 7 to get 5040.

$$5040\times 8\times 9\times 10$$

Multiply 5040 and 8 to get 40320.

$$40320\times 9\times 10$$

Multiply 40320 and 9 to get 362880.

$$362880\times 10$$

Multiply 362880 and 10 to get 3628800.

$$3628800$$

Factor

$$2^{8}\times 3^{4}\times 5^{2}\times 7$$
