Given numbers are 865, 361, 158, 840

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 361 are 19 x 19

Prime factors of 158 are 2 x 79

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 865, 361, 158, 840

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

Apply this formula for all numbers.

Step1:

LCM(865, 361) = 312265

GCD(865, 361) = ( 865 x 361 ) / 312265

= 865 / 361

= 865

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 865, 361, 158, 840 is 1
