Given numbers are 865, 148, 247, 684

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 148 are 2 x 2 x 37

Prime factors of 247 are 13 x 19

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 865, 148, 247, 684

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

Apply this formula for all numbers.

Step1:

LCM(865, 148) = 128020

GCD(865, 148) = ( 865 x 148 ) / 128020

= 865 / 148

= 865

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 865, 148, 247, 684 is 1
