Yes - the previous multiple of 4, 1900, as a year divisible by 100, would also require to be divisible by 400 in order to be a leap year - which it is not. While 2000 is divisible by 400, 2100, 2200 and 2300 are not, and therefore none of those three will be a leap year.

1900 was also the last year of the 19t century, so 1904 would've been the first leap year ever of the 20th century regardless if 1900 was a leap year or not. Even if 1900 was a triple leap year because it was divisible by 475, anything else would've been ignored by the time 1905 came.
