`(173xx173xx173+127xx127xx127)/(173xx173-173xx127+127xx127)=`

Simplify: (173x173x173+127x127x127)/(173x173-173x127+127x127)

Simplify: (173\ xx\ 173\ xx\ 173+127\ xx\ 127\ xx\ 127)/(173\ xx\ 173-173\ xx\ 127+127\ xx\ 127)

Q. 127 to 151

If a = 3 ^(129) xx 5 ^(128) xx 7 ^(22) b = 3 ^(128) xx 5 ^(129) xx 7 ^(21) c = 3 ^(127)xx 5 ^(128) xx 7 ^(23) d = 3 ^(127) xx 5 ^(128) xx 7 ^(24) , then HCF of a,b,c and d is

If a = 3^(129) xx 5^128 xx 7^22 b = 3^128 xx 5^129 xx 7^21 c = 3^127 xx 5^128 xx 7^24 , then HCF of a,b, and c is
