Answer 1

#27#

This method uses only #color(blue)"subtraction"# to find the GCF.
#•" subtract smaller number from larger number"#
#•" Repeat this until a common value is obtained"#
#•" The common value is the GCF"#
#" The starting numbers are 81 and 27"#
#rArr81-27=54rarr" numbers are now 54 and 27"#
#rArr54-27=27rarr" numbers are now 27 and 27"#
#" common value of 27 reached"#
