Given numbers are 402, 905, 764, 912

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 905 are 5 x 181

Prime factors of 764 are 2 x 2 x 191

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 402, 905, 764, 912

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

Apply this formula for all numbers.

Step1:

LCM(402, 905) = 363810

GCD(402, 905) = ( 402 x 905 ) / 363810

= 402 / 905

= 402

Step2:

LCM(1, 764) = 764

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

= 1 / 764

= 1

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 402, 905, 764, 912 is 1
