Given numbers are 805, 988, 768, 505

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 988 are 2 x 2 x 13 x 19

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

Prime factors of 505 are 5 x 101

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

Given numbers are 805, 988, 768, 505

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

Apply this formula for all numbers.

Step1:

LCM(805, 988) = 795340

GCD(805, 988) = ( 805 x 988 ) / 795340

= 805 / 988

= 805

Step2:

LCM(1, 768) = 768

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

= 1 / 768

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 805, 988, 768, 505 is 1
