Given numbers are 985, 438, 805, 569

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

Apply this formula for all numbers.

Step1:

LCM(985, 438) = 431430

GCD(985, 438) = ( 985 x 438 ) / 431430

= 985 / 438

= 985

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 569) = 569

GCD(1, 569) = ( 1 x 569 ) / 569

= 1 / 569

= 1

So, Greatest Common Divisor of 985, 438, 805, 569 is 1
