Given numbers are 865, 374, 840, 393

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 374 are 2 x 11 x 17

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

Prime factors of 393 are 3 x 131

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

Given numbers are 865, 374, 840, 393

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

Apply this formula for all numbers.

Step1:

LCM(865, 374) = 323510

GCD(865, 374) = ( 865 x 374 ) / 323510

= 865 / 374

= 865

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 865, 374, 840, 393 is 1
