Given numbers are 171, 361, 343, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 361) = 3249
GCD(171, 361) = ( 171 x 361 ) / 3249
= 171 / 361
= 171
Step2:
LCM(19, 343) = 6517
GCD(19, 343) = ( 19 x 343 ) / 6517
= 19 / 343
= 19
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 171, 361, 343, 247 is 1
