Given numbers are 251, 159, 789, 930

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

Apply this formula for all numbers.

Step1:

LCM(251, 159) = 39909

GCD(251, 159) = ( 251 x 159 ) / 39909

= 251 / 159

= 251

Step2:

LCM(1, 789) = 789

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

= 1 / 789

= 1

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 251, 159, 789, 930 is 1
