Given numbers are 209, 638, 278, 471

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

Apply this formula for all numbers.

Step1:

LCM(209, 638) = 12122

GCD(209, 638) = ( 209 x 638 ) / 12122

= 209 / 638

= 209

Step2:

LCM(11, 278) = 3058

GCD(11, 278) = ( 11 x 278 ) / 3058

= 11 / 278

= 11

Step3:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

So, Greatest Common Divisor of 209, 638, 278, 471 is 1
