1 - insufficient. take d=2, d=3. 100 and 1000 are factors of 30!

2 - insufficient. again, d could be anything

30! has 7 zeroes (5*2, 10, 15*4, 20, 25*8, 30 all yield zeroes). So,
knowing that d>6 is sufficient

I was wondering where GCF and LCM are in the previous question :-)

Product of 2 numbers = LCM * GCF

[ For reference: https://en.wikipedia.org/wiki/Greatest_c ... ng_the_gcd ]

We can clearly see that either (1) or (2) by itself is not sufficient
