Question

5. 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 + 7 x 5 x 3 is a composite number. Explain​

Answer 1

Step-by-step explanation:

$(8 \times \times \times 6 \times 5 \times 4 \times 3 \times 2 \times 1) + (7 \times 5 \times 3) \\ = 40320 + 105 \\ = 40425$

40425 is divisible by 5, 3,etc.

Thus, a number which has more than two factors is a composite number.

Thus, the given number is a composite number.

hence the result.
