Solve 7*6*5*4-5*4*3*2-6

$$7 \times 6 \times 5 \times 4-5 \times 4 \times 3 \times 2-6$$

Evaluate

$$714$$

Solution Steps

Multiply 7 and 6 to get 42.

$$42\times 5\times 4-5\times 4\times 3\times 2-6$$

Multiply 42 and 5 to get 210.

$$210\times 4-5\times 4\times 3\times 2-6$$

Multiply 210 and 4 to get 840.

$$840-5\times 4\times 3\times 2-6$$

Multiply 5 and 4 to get 20.

$$840-20\times 3\times 2-6$$

Multiply 20 and 3 to get 60.

$$840-60\times 2-6$$

Multiply 60 and 2 to get 120.

$$840-120-6$$

Subtract 120 from 840 to get 720.

$$720-6$$

Subtract 6 from 720 to get 714.

$$714$$

Factor

$$2\times 3\times 7\times 17$$
