Question

explain 5×4×3×2×1+5 and 17× 15 ×13×11×9×7×5×3×1+7 are composite numbers​

Answer 1

Answer:

1. 5 * 4 * 3 * 2 * 1 + 5

= 5 ( 5 * 4 * 3 * 2 * 1 + 1 )

= 5 ( 120 + 1 )

= 5 ( 121)

Since it has more than two factors , it is a composite number.

i.e., Since 121 cannot be divided by just 1 and 121, it is a composite number.

The number 605 can be evenly divided by 1, 5, 11, 55, 121 and 605, with no remainder

2. 17 * 15 * 13 * 11 * 9 * 7 * 5 * 3 * 1 + 7

= 7 ( 17 * 15 * 13 * 11 * 9 * 7 * 5 * 3 * 1 + 1 )

= 7 ( 34459425 + 1)

= 7 ( 34459426 )

Since it has more than two factors , it is a composite number.

The number 34,459,426 can be evenly divided by 1, 2, 19, 38, 43, 86, 817, 1,634, 21,089, 42,178, 400,691, 801,382, 906,827, 1,813,654, 17,229,713 and 34,459,426, with no remainder.
