Given numbers are 689, 764, 755

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

Apply this formula for all numbers.

Step1:

LCM(689, 764) = 526396

GCD(689, 764) = ( 689 x 764 ) / 526396

= 689 / 764

= 689

Step2:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 689, 764, 755 is 1
