Given numbers are 690, 465, 227, 505

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 465 are 3 x 5 x 31

Prime factors of 227 are 227

Prime factors of 505 are 5 x 101

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

Given numbers are 690, 465, 227, 505

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

Apply this formula for all numbers.

Step1:

LCM(690, 465) = 21390

GCD(690, 465) = ( 690 x 465 ) / 21390

= 690 / 465

= 690

Step2:

LCM(15, 227) = 3405

GCD(15, 227) = ( 15 x 227 ) / 3405

= 15 / 227

= 15

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 690, 465, 227, 505 is 1
