Phigol

Phigol is equal to \(\lfloor 10^{99}\phi \rfloor\), or the first 100 digits of \(\phi\) without the decimal point.A googol is a tiny dot Its full decimal expansion is:
Its prime factorization is 3 × 8,342,699,992,611,683 × 200,346,780,527,216,943,982,143,179,768,801,147 × 322,683,969,787,780,736,862,368,046,487,637,814,725,351,618,779.
