Given numbers are 943, 680, 290, 649

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

Apply this formula for all numbers.

Step1:

LCM(943, 680) = 641240

GCD(943, 680) = ( 943 x 680 ) / 641240

= 943 / 680

= 943

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 943, 680, 290, 649 is 1
