Given numbers are 145, 256, 308, 109

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 109 are 109

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

Given numbers are 145, 256, 308, 109

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

Apply this formula for all numbers.

Step1:

LCM(145, 256) = 37120

GCD(145, 256) = ( 145 x 256 ) / 37120

= 145 / 256

= 145

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

So, Greatest Common Divisor of 145, 256, 308, 109 is 1
