Given numbers are 685, 986, 869, 543

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

Apply this formula for all numbers.

Step1:

LCM(685, 986) = 675410

GCD(685, 986) = ( 685 x 986 ) / 675410

= 685 / 986

= 685

Step2:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 685, 986, 869, 543 is 1
