Given numbers are 789, 153, 555, 620

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

Apply this formula for all numbers.

Step1:

LCM(789, 153) = 40239

GCD(789, 153) = ( 789 x 153 ) / 40239

= 789 / 153

= 789

Step2:

LCM(3, 555) = 555

GCD(3, 555) = ( 3 x 555 ) / 555

= 3 / 555

= 3

Step3:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

So, Greatest Common Divisor of 789, 153, 555, 620 is 1
