Given numbers are 689, 668, 745, 571

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

Apply this formula for all numbers.

Step1:

LCM(689, 668) = 460252

GCD(689, 668) = ( 689 x 668 ) / 460252

= 689 / 668

= 689

Step2:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

Step3:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

So, Greatest Common Divisor of 689, 668, 745, 571 is 1
