Given numbers are 258, 109, 276, 660

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 109 are 109

Prime factors of 276 are 2 x 2 x 3 x 23

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

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

Given numbers are 258, 109, 276, 660

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

Apply this formula for all numbers.

Step1:

LCM(258, 109) = 28122

GCD(258, 109) = ( 258 x 109 ) / 28122

= 258 / 109

= 258

Step2:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 258, 109, 276, 660 is 1
