Given numbers are 603, 689, 565, 655

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

Apply this formula for all numbers.

Step1:

LCM(603, 689) = 415467

GCD(603, 689) = ( 603 x 689 ) / 415467

= 603 / 689

= 603

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 655) = 655

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

= 1 / 655

= 1

So, Greatest Common Divisor of 603, 689, 565, 655 is 1
