take into account

1.take someone or something into account and take into account someone or something (to remember to consider someone or something)

2.take something into account and take something into consideration

(to consider something to be an important factor in some decision.)

take something/somebody into account also take account of something/somebody (to think about something or someone when you are making a decision or a judgement)

take something into account also take account of something (to include something when making a decision or judgment)

I am wondering if would you take into account their difference? or are they interchangeable? if so, when, where, or in which situation?
