Given numbers are 285, 656, 276, 836

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 276 are 2 x 2 x 3 x 23

Prime factors of 836 are 2 x 2 x 11 x 19

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

Given numbers are 285, 656, 276, 836

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, 276) = 276

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

= 1 / 276

= 1

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 285, 656, 276, 836 is 1
