Given numbers are 689, 132, 390, 569

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

Apply this formula for all numbers.

Step1:

LCM(689, 132) = 90948

GCD(689, 132) = ( 689 x 132 ) / 90948

= 689 / 132

= 689

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 569) = 569

GCD(1, 569) = ( 1 x 569 ) / 569

= 1 / 569

= 1

So, Greatest Common Divisor of 689, 132, 390, 569 is 1
