Given numbers are 168, 263, 329, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 263) = 44184
GCD(168, 263) = ( 168 x 263 ) / 44184
= 168 / 263
= 168
Step2:
LCM(1, 329) = 329
GCD(1, 329) = ( 1 x 329 ) / 329
= 1 / 329
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 168, 263, 329, 398 is 1
