Given numbers are 309, 377, 828, 168

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 377 are 13 x 29

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 309, 377, 828, 168

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

Apply this formula for all numbers.

Step1:

LCM(309, 377) = 116493

GCD(309, 377) = ( 309 x 377 ) / 116493

= 309 / 377

= 309

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 309, 377, 828, 168 is 1
