Given numbers are 991, 438, 939, 767

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

Apply this formula for all numbers.

Step1:

LCM(991, 438) = 434058

GCD(991, 438) = ( 991 x 438 ) / 434058

= 991 / 438

= 991

Step2:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

Step3:

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

= 1 / 767

= 1

So, Greatest Common Divisor of 991, 438, 939, 767 is 1
