The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 215 are 5 x 43

Prime factors of 469 are 7 x 67

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 154, 215, 469, 392

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

Apply this formula for all numbers.

Step1:

LCM(154, 215) = 33110

GCD(154, 215) = ( 154 x 215 ) / 33110

= 154 / 215

= 154

Step2:

LCM(1, 469) = 469

GCD(1, 469) = ( 1 x 469 ) / 469

= 1 / 469

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 154, 215, 469, 392 is 1
