The factor cake shows that the prime factorization of 2020 is 2 × 2 × 5 × 101. We can write that more compactly: 2020 = 2² × 5 × 101.

In case you would like a still picture of the cake instead of the gif, here it is:

I will write more about the number 2020 before tomorrow. Enjoy saying good-bye to 2019 and getting ready for the new year!
