Given numbers are 947, 398, 391, 559

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

Apply this formula for all numbers.

Step1:

LCM(947, 398) = 376906

GCD(947, 398) = ( 947 x 398 ) / 376906

= 947 / 398

= 947

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 559) = 559

GCD(1, 559) = ( 1 x 559 ) / 559

= 1 / 559

= 1

So, Greatest Common Divisor of 947, 398, 391, 559 is 1
