Given numbers are 191, 792, 203, 780

The list of prime factors of all numbers are

Prime factors of 191 are 191

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 203 are 7 x 29

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 191, 792, 203, 780

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

Apply this formula for all numbers.

Step1:

LCM(191, 792) = 151272

GCD(191, 792) = ( 191 x 792 ) / 151272

= 191 / 792

= 191

Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 191, 792, 203, 780 is 1
