Given numbers are 209, 272, 649, 303

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

Apply this formula for all numbers.

Step1:

LCM(209, 272) = 56848

GCD(209, 272) = ( 209 x 272 ) / 56848

= 209 / 272

= 209

Step2:

LCM(1, 649) = 649

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

= 1 / 649

= 1

Step3:

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

= 1 / 303

= 1

So, Greatest Common Divisor of 209, 272, 649, 303 is 1
