The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 805 are 5 x 7 x 23

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

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 782, 805, 636, 920

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

Apply this formula for all numbers.

Step1:

LCM(782, 805) = 27370

GCD(782, 805) = ( 782 x 805 ) / 27370

= 782 / 805

= 782

Step2:

LCM(23, 636) = 14628

GCD(23, 636) = ( 23 x 636 ) / 14628

= 23 / 636

= 23

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 782, 805, 636, 920 is 1
