Using the short scale definitions from the table here: https://en.wikipedia.org/wiki/Names_of_large_numbers

 72.1 Quadrillion = 72.1 × 1015 = 72.1 × 1015 = 7.21 × 1016 = 72 100 000 000 000 000 ___ ___ ___ ___ 1000 Trillion × 72 = 103 × 1012 × 72 = 72 × 1015 = 7.2 × 1016 = 72 000 000 000 000 000

So  72.1 Quadrillion  is pretty close to  100 Trillion × 72  but they're not exactly the same.

( If you use the long scale definitions you get  72.1 × 1024  and  72 × 1021   which are further apart.)

And neither are equal to  1072  .   1072  is  1  with  72  zeros after it.

1072  =  1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000
