Given numbers are 156, 798, 557, 789

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

Apply this formula for all numbers.

Step1:

LCM(156, 798) = 20748

GCD(156, 798) = ( 156 x 798 ) / 20748

= 156 / 798

= 156

Step2:

LCM(6, 557) = 3342

GCD(6, 557) = ( 6 x 557 ) / 3342

= 6 / 557

= 6

Step3:

LCM(1, 789) = 789

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

= 1 / 789

= 1

So, Greatest Common Divisor of 156, 798, 557, 789 is 1
