Given numbers are 203, 103, 754, 643

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

Apply this formula for all numbers.

Step1:

LCM(203, 103) = 20909

GCD(203, 103) = ( 203 x 103 ) / 20909

= 203 / 103

= 203

Step2:

LCM(1, 754) = 754

GCD(1, 754) = ( 1 x 754 ) / 754

= 1 / 754

= 1

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 203, 103, 754, 643 is 1
