Given numbers are 398, 339, 685, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 339) = 134922
GCD(398, 339) = ( 398 x 339 ) / 134922
= 398 / 339
= 398
Step2:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 398, 339, 685, 531 is 1
