Given numbers are 565, 649, 628, 609

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

Apply this formula for all numbers.

Step1:

LCM(565, 649) = 366685

GCD(565, 649) = ( 565 x 649 ) / 366685

= 565 / 649

= 565

Step2:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 565, 649, 628, 609 is 1
