as a number one hundred forty seven thousand, 2 hundred and fifty eight if talking to someone. however if you are telling someone who may want to write it. you could also say each number after each other e.g. 1, 4, 7, 2, 5, 8 or as 2 digit numbers 14, 72, 58
2300 either 23 100 or 2000 300 or 23 double 0.
132 one hundred and 32.
2032 either 20 32 or 2000 and 32
Again there is a big difference between saying a number and saying a sequence of numbers that someone need to write down e.g. telephone numbers. This is why you may hear 132 be describes as 1, 3, 2 or 13, 2 or 1, 32 or 132.
