Answer :
the Prime factorization of 4a
is 2*2*a
the Prime factorization of 9a^4
is 3*3*a*a*a*a
they only have 1 a in common
therefore the Greatest Common Factor (GCF)
that 4a and 9a^4 have
is a
is 2*2*a
the Prime factorization of 9a^4
is 3*3*a*a*a*a
they only have 1 a in common
therefore the Greatest Common Factor (GCF)
that 4a and 9a^4 have
is a
