Select one:
O a. 2272
O b. 2388
O c. 2414

Answer 1

Answer:

d) 2310

13860 (divided by 2 ; first prime number)

we get 6930.

again 6930 (divided by 3; second prime number)

we get 2310

and 2310 (divided by 5; which is next prime number)

we get 462

462 (divided by 7)

we get 66

and 66 ( divided by 11 ; the next prime number after 7)
