Given numbers are 408, 504, 977, 305

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 977 are 977

Prime factors of 305 are 5 x 61

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

Given numbers are 408, 504, 977, 305

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

Apply this formula for all numbers.

Step1:

LCM(408, 504) = 8568

GCD(408, 504) = ( 408 x 504 ) / 8568

= 408 / 504

= 408

Step2:

LCM(24, 977) = 23448

GCD(24, 977) = ( 24 x 977 ) / 23448

= 24 / 977

= 24

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 408, 504, 977, 305 is 1
