The last digit must be one that fills all of the right-most segments. So it can only be 1, 3, 4, 7, 8, 9, 0.
You can eliminate 1, 4, 7 and 0, as they would leave gaps that can't be filled. So you know the last digit must be a 3, 8, or 9. Try from there...
I don't see how certain numbers can be used following the rules - a 4 would always leave an unused segment at the top, wouldn't it? I must admit that I'm stumped too.

What do you by a segment?
Each of the elongated shapes that you can shade in. '8' takes up seven segments, '1' takes up only two, for example..
Does this mean that every single segment in the diagram must be shaded (“used”) by the numbers?
Correct. Every single segment is used, and only used once (no overlapping).
Thx. Got it now!
I am so stuck i can't get my head around this at all
No matter what I pick I can't get out of only using 8 or 3 haha
Are all four numbers in the normal orientation?
Yes, normal orientation, digital numbers.
I am stuck, can i get the first digit?
Try working backwards instead:

Correct. 4 cannot be one of the numbers.
Does "no digits repeated" mean they can't be right next to each other, but they can be used twice?
No. The answer is four unique digits.
Thanks!
I'm stuck on this one what segment do I start from
Could I possibly have the first digit please I have 3 numbers just having trouble on last digit
