The list of prime factors of all numbers are

Prime factors of 491 are 491

Prime factors of 802 are 2 x 401

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

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 491, 802, 840, 768

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

Apply this formula for all numbers.

Step1:

LCM(491, 802) = 393782

GCD(491, 802) = ( 491 x 802 ) / 393782

= 491 / 802

= 491

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 491, 802, 840, 768 is 1
