Given numbers are 255, 595, 990, 789

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

Apply this formula for all numbers.

Step1:

LCM(255, 595) = 1785

GCD(255, 595) = ( 255 x 595 ) / 1785

= 255 / 595

= 255

Step2:

LCM(85, 990) = 16830

GCD(85, 990) = ( 85 x 990 ) / 16830

= 85 / 990

= 85

Step3:

LCM(5, 789) = 3945

GCD(5, 789) = ( 5 x 789 ) / 3945

= 5 / 789

= 5

So, Greatest Common Divisor of 255, 595, 990, 789 is 1
