Given numbers are 813, 135, 622, 688

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

Apply this formula for all numbers.

Step1:

LCM(813, 135) = 36585

GCD(813, 135) = ( 813 x 135 ) / 36585

= 813 / 135

= 813

Step2:

LCM(3, 622) = 1866

GCD(3, 622) = ( 3 x 622 ) / 1866

= 3 / 622

= 3

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 813, 135, 622, 688 is 1
