#GCF =1#

#2 and 5# are prime numbers, so the only factor they have in common is #1#

#6# shares the factor of #2# with #2#, but apart from #1# has no common factor with #5#

The following are the products of the factors;

#2 =1xx2#
#5 =1color(white)(wwwww)xx5#
#6 = 1xx2xx3#

It is clear that the only factor they have in common is #1#

#1# is the only number that can be evenly divided into all three of those numbers.

#2xx3=6#
#5xx3=15#
#6xx3=18#

#2xx2=4#
#5xx2=10#
#6xx2=12#

#2xx1=2#
#5xx1=5#
#6xx1=6#
