Given numbers are 801, 688, 691

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

Apply this formula for all numbers.

Step1:

LCM(801, 688) = 551088

GCD(801, 688) = ( 801 x 688 ) / 551088

= 801 / 688

= 801

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 801, 688, 691 is 1
