Given numbers are 685, 286, 731, 127

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

Apply this formula for all numbers.

Step1:

LCM(685, 286) = 195910

GCD(685, 286) = ( 685 x 286 ) / 195910

= 685 / 286

= 685

Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

Step3:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

So, Greatest Common Divisor of 685, 286, 731, 127 is 1
