SCP-1941's number

SCP-1941 is an entry on the website. The SCP Foundation is a creative writing wiki centered around the fictional namesake organization that catalogs, studies and contains objects that violate natural law.
==Description==
SCP-1941 is an alien that landed on the Moon and began constructing a network of black web-like structures on the far side of the Moon. The probe will stop the replication of itself once a signal has been received from humanity as concerns the factors of the following integer:
\(2^{2^{79}}+3^{2^{83}}+5^{2^{89}}+7^{2^{97}}\)scp-wiki.net/scp-1941
The first two prime factors of this number are 3 and 487811, and there are no other prime factors underneath \(2 \times 10^9\) according to a Japanese Googology Wiki user LPer NATTO. LPer NATTO, LPerNATTO/SCP1941, GitHub. (The source code to compute prime factors.) The magnitude of this number is approximately \(10^{10^{29.126}}\), or a googol squared repeatedly just over 94 times.
