Given numbers are 261, 660, 634, 608

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 634 are 2 x 317

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

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

Given numbers are 261, 660, 634, 608

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

Apply this formula for all numbers.

Step1:

LCM(261, 660) = 57420

GCD(261, 660) = ( 261 x 660 ) / 57420

= 261 / 660

= 261

Step2:

LCM(3, 634) = 1902

GCD(3, 634) = ( 3 x 634 ) / 1902

= 3 / 634

= 3

Step3:

LCM(1, 608) = 608

GCD(1, 608) = ( 1 x 608 ) / 608

= 1 / 608

= 1

So, Greatest Common Divisor of 261, 660, 634, 608 is 1
