4789

Number of digits of sum of digits (28): 2
Number of digits of product of digits (2016): 4
Number of digits of sum of squares (210): 3

It's a prime number, and the others are triangular.

I just used the same excel document from the previous problem and hoped the number satisfies a<b<c<d

It was easy, got rid of all the values that give different number digits for sum of digits, sum of squares and product of digits. I was left with only 19 possible solutions
