Given numbers are 399, 178, 149, 764

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

Apply this formula for all numbers.

Step1:

LCM(399, 178) = 71022

GCD(399, 178) = ( 399 x 178 ) / 71022

= 399 / 178

= 399

Step2:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 399, 178, 149, 764 is 1
