Given numbers are 398, 211, 603, 653

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

Apply this formula for all numbers.

Step1:

LCM(398, 211) = 83978

GCD(398, 211) = ( 398 x 211 ) / 83978

= 398 / 211

= 398

Step2:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 398, 211, 603, 653 is 1
