GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 361) = 143678
GCD(398, 361) = ( 398 x 361 ) / 143678
= 398 / 361
= 398
Step2:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
Step3:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
So, Greatest Common Divisor of 398, 361, 289, 711 is 1
