Given numbers are 711, 390, 438, 764

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 438 are 2 x 3 x 73

Prime factors of 764 are 2 x 2 x 191

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 711, 390, 438, 764

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

Apply this formula for all numbers.

Step1:

LCM(711, 390) = 92430

GCD(711, 390) = ( 711 x 390 ) / 92430

= 711 / 390

= 711

Step2:

LCM(3, 438) = 438

GCD(3, 438) = ( 3 x 438 ) / 438

= 3 / 438

= 3

Step3:

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

= 3 / 764

= 3

So, Greatest Common Divisor of 711, 390, 438, 764 is 1
