Given numbers are 831, 789, 180, 157

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

Apply this formula for all numbers.

Step1:

LCM(831, 789) = 218553

GCD(831, 789) = ( 831 x 789 ) / 218553

= 831 / 789

= 831

Step2:

LCM(3, 180) = 180

GCD(3, 180) = ( 3 x 180 ) / 180

= 3 / 180

= 3

Step3:

LCM(3, 157) = 471

GCD(3, 157) = ( 3 x 157 ) / 471

= 3 / 157

= 3

So, Greatest Common Divisor of 831, 789, 180, 157 is 1
