Given numbers are 289, 487, 636, 635

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

Apply this formula for all numbers.

Step1:

LCM(289, 487) = 140743

GCD(289, 487) = ( 289 x 487 ) / 140743

= 289 / 487

= 289

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 289, 487, 636, 635 is 1
