What is 7777777 in German?

The number 7777777 in German is written out as sieben Millionen siebenhundert siebenundsiebzigtausend siebenhundert siebenundsiebzig. German builds large numbers in a very logical but long compound system. To understand it, you break it into chunks. Seven million is sieben Millionen, note that Millionen is plural. Then 777,000 is siebenhundert siebenundsiebzigtausend, literally seven hundred seven and seventy thousand. The German system for numbers under 100 is reversed compared to English, you say the ones before the tens, so 77 is not seventy seven but seven and seventy, siebenundsiebzig. Finally 777 is siebenhundert siebenundsiebzig. Put together you get the full word, which in German is written as one extremely long word without spaces, but for readability it is often written with spaces when teaching foreigners. Germans would in everyday life almost never say this full form and would just say the digits individually, especially for a phone number like 7777777 which would be read as sieben sieben sieben sieben sieben sieben sieben, or use the number seven million etc. for an amount.
