Given numbers are 431, 126, 643, 683

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

Apply this formula for all numbers.

Step1:

LCM(431, 126) = 54306

GCD(431, 126) = ( 431 x 126 ) / 54306

= 431 / 126

= 431

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

So, Greatest Common Divisor of 431, 126, 643, 683 is 1
