Given numbers are 768, 381, 307, 991

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

Apply this formula for all numbers.

Step1:

LCM(768, 381) = 97536

GCD(768, 381) = ( 768 x 381 ) / 97536

= 768 / 381

= 768

Step2:

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

= 3 / 307

= 3

Step3:

LCM(1, 991) = 991

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

= 1 / 991

= 1

So, Greatest Common Divisor of 768, 381, 307, 991 is 1
