Given numbers are 798, 819, 921, 247

The list of prime factors of all numbers are

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 921 are 3 x 307

Prime factors of 247 are 13 x 19

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

Given numbers are 798, 819, 921, 247

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

Apply this formula for all numbers.

Step1:

LCM(798, 819) = 31122

GCD(798, 819) = ( 798 x 819 ) / 31122

= 798 / 819

= 798

Step2:

LCM(21, 921) = 6447

GCD(21, 921) = ( 21 x 921 ) / 6447

= 21 / 921

= 21

Step3:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

So, Greatest Common Divisor of 798, 819, 921, 247 is 1
