Given numbers are 646, 382, 203, 773

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

Apply this formula for all numbers.

Step1:

LCM(646, 382) = 123386

GCD(646, 382) = ( 646 x 382 ) / 123386

= 646 / 382

= 646

Step2:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 646, 382, 203, 773 is 1
