Given numbers are 688, 928, 861, 763

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

Apply this formula for all numbers.

Step1:

LCM(688, 928) = 39904

GCD(688, 928) = ( 688 x 928 ) / 39904

= 688 / 928

= 688

Step2:

LCM(16, 861) = 13776

GCD(16, 861) = ( 16 x 861 ) / 13776

= 16 / 861

= 16

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 688, 928, 861, 763 is 1
