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

Apply this formula for all numbers.

Step1:

LCM(628, 789) = 495492

GCD(628, 789) = ( 628 x 789 ) / 495492

= 628 / 789

= 628

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 628, 789, 158 is 1
