Given numbers are 285, 656, 278, 233

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 278 are 2 x 139

Prime factors of 233 are 233

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

Given numbers are 285, 656, 278, 233

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

Apply this formula for all numbers.

Step1:

LCM(285, 656) = 186960

GCD(285, 656) = ( 285 x 656 ) / 186960

= 285 / 656

= 285

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 233) = 233

GCD(1, 233) = ( 1 x 233 ) / 233

= 1 / 233

= 1

So, Greatest Common Divisor of 285, 656, 278, 233 is 1
