Given numbers are 865, 687, 530, 154

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 687 are 3 x 229

Prime factors of 530 are 2 x 5 x 53

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 865, 687, 530, 154

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

Apply this formula for all numbers.

Step1:

LCM(865, 687) = 594255

GCD(865, 687) = ( 865 x 687 ) / 594255

= 865 / 687

= 865

Step2:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 865, 687, 530, 154 is 1
