Given numbers are 781, 551, 828, 804

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 551 are 19 x 29

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 804 are 2 x 2 x 3 x 67

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

Given numbers are 781, 551, 828, 804

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

Apply this formula for all numbers.

Step1:

LCM(781, 551) = 430331

GCD(781, 551) = ( 781 x 551 ) / 430331

= 781 / 551

= 781

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

= 1 / 804

= 1

So, Greatest Common Divisor of 781, 551, 828, 804 is 1
