NB When finding the s of a number. Inspect the number. If it is even , as in this case (306 ; endsc in ;6;) , then it will divide by '2'.

Hence

2 x X = 306

X = 306/2 = 153

So the first pair on numbers are 2 & 153.

Further inspection of the number, indicates it is a factor of '3' .

3 x X = 306

X = 306/3 = 102

So a second pair of numbers are 3 & 102

NB When finding the factors of a number.

If it ends in an even number (2,4,6,8,0) , then it will divide by '2'

If it ends in '0' or '5' , then it will divide by '5'.

If the digits sum to '9' , then it will divide by '9' ( 306 ; 3 + 0 + 6 = 9), So 306 will divide by '9' . Hence 34

The only two number you have painstakingly check are '3' & '7'.
