Jianing Song, Table of n, a(n) for n = 1..8435 (all terms <= 50000)
EXAMPLE
15 is a term since the prime factors of 15 are 3,5, and we have gpf(15+3) = 3 and gpf(15+5) = 5.
PROG
(PARI) gpf(n) = vecmax(factor(n)[, 1]);
isA354525(n) = my(f=factor(n)[, 1]); for(i=1, #f, if(gpf(n+f[i])!=f[i], return(0))); 1
