Question 61838
I'm not sure what you want, I'm going to take a chance that you want the GCF.
{{{21a^3*b^2*c^4}}}, {{{28a^2*b^3*c^6}}},  {{{32ab^4*c^5}}}
{{{ab^2*c^4(21a^2)}}}, {{{ab^2*c^4(28abc^2)}}}, {{{ab^2*c^4(32b^2c)}}}
The GCF is {{{highlight(ab^2*c^4)}}}
Let me know if your instructions require something else.
Happy Calculating!!!
