Given numbers are 689, 688, 904, 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, 688) = 474032

GCD(689, 688) = ( 689 x 688 ) / 474032

= 689 / 688

= 689

Step2:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

Step3:

LCM(1, 797) = 797

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

= 1 / 797

= 1

So, Greatest Common Divisor of 689, 688, 904, 797 is 1
