The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 877 are 877

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

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

Given numbers are 655, 877, 840, 408

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

Apply this formula for all numbers.

Step1:

LCM(655, 877) = 574435

GCD(655, 877) = ( 655 x 877 ) / 574435

= 655 / 877

= 655

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 655, 877, 840, 408 is 1
