What is the least number actual number that rounds to 400’000 and 370’000

So what you do is round the 7 in 370,000.

What my teacher would always say is 4 and below let it go so keep it the same.

And, 5 and above give it a shove so go to the next number above whatever number it is after that number that you are rounding➕➖✖➗:)

So yes it wo;uld be 400000,\
