The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 565 are 5 x 113

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

Given numbers are 655, 882, 390, 565

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

Apply this formula for all numbers.

Step1:

LCM(655, 882) = 577710

GCD(655, 882) = ( 655 x 882 ) / 577710

= 655 / 882

= 655

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

So, Greatest Common Divisor of 655, 882, 390, 565 is 1
