Given numbers are 398, 431, 408, 563

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(398, 431) = 171538

GCD(398, 431) = ( 398 x 431 ) / 171538

= 398 / 431

= 398

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 398, 431, 408, 563 is 1
