Given numbers are 402, 617, 589, 655

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

Apply this formula for all numbers.

Step1:

LCM(402, 617) = 248034

GCD(402, 617) = ( 402 x 617 ) / 248034

= 402 / 617

= 402

Step2:

LCM(1, 589) = 589

GCD(1, 589) = ( 1 x 589 ) / 589

= 1 / 589

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 402, 617, 589, 655 is 1
