Given numbers are 769, 788, 637, 686

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

Apply this formula for all numbers.

Step1:

LCM(769, 788) = 605972

GCD(769, 788) = ( 769 x 788 ) / 605972

= 769 / 788

= 769

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 769, 788, 637, 686 is 1
