Given numbers are 865, 636, 603, 403

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 603 are 3 x 3 x 67

Prime factors of 403 are 13 x 31

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

Given numbers are 865, 636, 603, 403

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

Apply this formula for all numbers.

Step1:

LCM(865, 636) = 550140

GCD(865, 636) = ( 865 x 636 ) / 550140

= 865 / 636

= 865

Step2:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 865, 636, 603, 403 is 1
