Given numbers are 668, 609, 583, 820

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

Apply this formula for all numbers.

Step1:

LCM(668, 609) = 406812

GCD(668, 609) = ( 668 x 609 ) / 406812

= 668 / 609

= 668

Step2:

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

= 1 / 583

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 668, 609, 583, 820 is 1
