1120
Well since it ends with 0 you know 10 is one of the factors.
1120
/ \
112 10
Since 112 ends with an even number we now one of the fctors is 2;
1120
/ \
112 10
/\ /\
56 2 5 2
Since 56 ends with an even number we now 2 is a divisor;
1120
/ \
112 10
/\ /\
56 2 5 2
/\
28 2
/\
14 2
/\
7 2
Now we can't go any further because both 7 and 2are prime numbers;
So our prime factoizaton would be;
7*2*2*2*2*5*2
