See the entire solution process below:

To find the Greatest Common Factor of these three terms we must first factor each term separately:

#70x^2 = 2 xx 5 xx 7 xx x xx x#

#30x^6 = 2 xx 5 xx 3 xx x xx x xx x xx x xx x xx x#

#90x^9 = 2 xx 5 xx 3 xx 3 xx x xx x xx x xx x xx x xx x xx x xx x xx x#

The Common Factors are:

#70x^2 = color(red)(2 xx 5) xx 7 xx color(red)(x xx x)#

#30x^6 = color(red)(2 xx 5) xx 3 xx color(red)(x xx x) xx x xx x xx x xx x#

#90x^9 = color(red)(2 xx 5) xx 3 xx 3 xx color(red)(x xx x) xx x xx x xx x xx x xx x xx x xx x#

Therefore the GCG (Greatest Common Factor) is:

#color(red)(2 xx 5 xx) color(red)(x xx x) = 10x^2#
