Answer 1

Step-by-step explanation:

Complete step-by-step answer:

Let us assume the four prime numbers to be ‘a’, ‘b’, ‘c’ and ‘d’.

As mentioned in the question, the product of the first three numbers is 385.

That is, the product of a, b and c is 385.

Therefore, abc = 385

Also, the product of the last three numbers is 1001.

That is, the product of b, c and d is 1001.

Therefore, bcd = 1001

so,

abc/ bcd = 385/1001

= 5/13

Therefore, we get the value of ‘a’ and ‘d’.

That is a = 5: d = 13

Therefore, as the smallest number in the ascending order series is ‘a’ , and the value of ‘a’ is 5, so the smallest number in the ascending order series is 5.
