To check
-
It is NOT an even number , so will not divide by '2'
-
It does NOT end in '5' , so will not divide by '5'.
-
The digits 381 do not sum to '9' ( 3+ 8 + 1= 12 = 3) So does not divide by '9'. 4. The clue is that the digits sum to '3' . Three is a Prime number , so it might divide by '3'. If so, then it is a composite number.
Hence
3)381 = 127 : No remainder.
So 127 X 3 = 381 / Hence it is a composite number.
NB When testing for composition of numbers, the other prime number to try is '7'.
