Given numbers are 871, 640, 612, 493

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 493 are 17 x 29

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

Given numbers are 871, 640, 612, 493

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

Apply this formula for all numbers.

Step1:

LCM(871, 640) = 557440

GCD(871, 640) = ( 871 x 640 ) / 557440

= 871 / 640

= 871

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 871, 640, 612, 493 is 1
