Given numbers are 136, 605, 987, 685

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

Apply this formula for all numbers.

Step1:

LCM(136, 605) = 82280

GCD(136, 605) = ( 136 x 605 ) / 82280

= 136 / 605

= 136

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 136, 605, 987, 685 is 1
