7abc - 7axy
7a (bc - xy) (7a is common, so take it out. You are left with bc from 7abc and -xy from 7axy)
7a (bc - xy) (7a is common, so take it out. You are left with bc from 7abc and -xy from 7axy)

the factor is 7a because that is the thing that both expressions have in common. you would write it like: 7a(bc-xy)
