Given numbers are 689, 178, 570

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

Apply this formula for all numbers.

Step1:

LCM(689, 178) = 122642

GCD(689, 178) = ( 689 x 178 ) / 122642

= 689 / 178

= 689

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 689, 178, 570 is 1
