Given numbers are 689, 406, 783, 797

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

Apply this formula for all numbers.

Step1:

LCM(689, 406) = 279734

GCD(689, 406) = ( 689 x 406 ) / 279734

= 689 / 406

= 689

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

So, Greatest Common Divisor of 689, 406, 783, 797 is 1
