Given numbers are 255, 660, 500, 308

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

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

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

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

Given numbers are 255, 660, 500, 308

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

Apply this formula for all numbers.

Step1:

LCM(255, 660) = 11220

GCD(255, 660) = ( 255 x 660 ) / 11220

= 255 / 660

= 255

Step2:

LCM(15, 500) = 1500

GCD(15, 500) = ( 15 x 500 ) / 1500

= 15 / 500

= 15

Step3:

LCM(5, 308) = 1540

GCD(5, 308) = ( 5 x 308 ) / 1540

= 5 / 308

= 5

So, Greatest Common Divisor of 255, 660, 500, 308 is 1
