Given numbers are 865, 678, 945, 556

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 678 are 2 x 3 x 113

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 865, 678, 945, 556

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

Apply this formula for all numbers.

Step1:

LCM(865, 678) = 586470

GCD(865, 678) = ( 865 x 678 ) / 586470

= 865 / 678

= 865

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 865, 678, 945, 556 is 1
