Given numbers are 679, 847, 477, 438

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

Apply this formula for all numbers.

Step1:

LCM(679, 847) = 82159

GCD(679, 847) = ( 679 x 847 ) / 82159

= 679 / 847

= 679

Step2:

LCM(7, 477) = 3339

GCD(7, 477) = ( 7 x 477 ) / 3339

= 7 / 477

= 7

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 679, 847, 477, 438 is 1
