Narrated Sahl bin Sa`d:
The Prophet (ﷺ) said, "Seventy-thousand or seven-hundred thousand of my followers (the narrator is in doubt as to the correct number) will enter Paradise holding each other till the first and the last of them enter Paradise at the same time, and their faces will have a glitter like that of the moon at night when it is full." Sahih Bukhari
This is Sahih hadees, which is narrated about a "dramatic entery", or a superb most enterance, I should say.
It is not about the total number from the whole Muslim nation, who would enter paradise,rather it mentions those who would enter in this superb manner.
The hadees from Ibn e Majah and Tirmizi is "Hasan", not sahih.
The figure would be somewhat like that,
70,000+(70,000x70)+ three handfulls of My Allah, SWT, the Most Merciful....
The 4970000 is the starting figure
