Given numbers are 136, 406, 688, 427

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

Apply this formula for all numbers.

Step1:

LCM(136, 406) = 27608

GCD(136, 406) = ( 136 x 406 ) / 27608

= 136 / 406

= 136

Step2:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

Step3:

LCM(2, 427) = 854

GCD(2, 427) = ( 2 x 427 ) / 854

= 2 / 427

= 2

So, Greatest Common Divisor of 136, 406, 688, 427 is 1
