Given numbers are 665, 161, 562, 392

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 161 are 7 x 23

Prime factors of 562 are 2 x 281

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 665, 161, 562, 392

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

Apply this formula for all numbers.

Step1:

LCM(665, 161) = 15295

GCD(665, 161) = ( 665 x 161 ) / 15295

= 665 / 161

= 665

Step2:

LCM(7, 562) = 3934

GCD(7, 562) = ( 7 x 562 ) / 3934

= 7 / 562

= 7

Step3:

LCM(1, 392) = 392

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

= 1 / 392

= 1

So, Greatest Common Divisor of 665, 161, 562, 392 is 1
