Given numbers are 689, 812, 695, 605

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

Apply this formula for all numbers.

Step1:

LCM(689, 812) = 559468

GCD(689, 812) = ( 689 x 812 ) / 559468

= 689 / 812

= 689

Step2:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 689, 812, 695, 605 is 1
