Given numbers are 789, 244, 475, 991

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

Apply this formula for all numbers.

Step1:

LCM(789, 244) = 192516

GCD(789, 244) = ( 789 x 244 ) / 192516

= 789 / 244

= 789

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 789, 244, 475, 991 is 1
