Evaluate 10!

Problem

10!

Solution

1. Identify the factorial notation n! which represents the product of all positive integers from n down to 1

2. Expand the expression into its individual integer factors.

10!=10×9×8×7×6×5×4×3×2×1

3. Multiply the numbers sequentially or in groups to find the total product.

10×9=90

90×8=720

720×7=5040

5040×6=30240

30240×5=151200

151200×4=604800

604800×3=1814400

1814400×2=3628800

3628800×1=3628800

Final Answer
