Given numbers are 822, 819, 989, 247

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

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

Prime factors of 989 are 23 x 43

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 822, 819, 989, 247

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

Apply this formula for all numbers.

Step1:

LCM(822, 819) = 224406

GCD(822, 819) = ( 822 x 819 ) / 224406

= 822 / 819

= 822

Step2:

LCM(3, 989) = 2967

GCD(3, 989) = ( 3 x 989 ) / 2967

= 3 / 989

= 3

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 822, 819, 989, 247 is 1
