Given numbers are 685, 274, 542, 122

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

Apply this formula for all numbers.

Step1:

LCM(685, 274) = 1370

GCD(685, 274) = ( 685 x 274 ) / 1370

= 685 / 274

= 685

Step2:

LCM(137, 542) = 74254

GCD(137, 542) = ( 137 x 542 ) / 74254

= 137 / 542

= 137

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 685, 274, 542, 122 is 1
