Given numbers are 172, 561, 499, 789

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

Apply this formula for all numbers.

Step1:

LCM(172, 561) = 96492

GCD(172, 561) = ( 172 x 561 ) / 96492

= 172 / 561

= 172

Step2:

LCM(1, 499) = 499

GCD(1, 499) = ( 1 x 499 ) / 499

= 1 / 499

= 1

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 172, 561, 499, 789 is 1
