Given numbers are 822, 842, 530, 979

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 842 are 2 x 421

Prime factors of 530 are 2 x 5 x 53

Prime factors of 979 are 11 x 89

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

Given numbers are 822, 842, 530, 979

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

Apply this formula for all numbers.

Step1:

LCM(822, 842) = 346062

GCD(822, 842) = ( 822 x 842 ) / 346062

= 822 / 842

= 822

Step2:

LCM(2, 530) = 530

GCD(2, 530) = ( 2 x 530 ) / 530

= 2 / 530

= 2

Step3:

LCM(2, 979) = 1958

GCD(2, 979) = ( 2 x 979 ) / 1958

= 2 / 979

= 2

So, Greatest Common Divisor of 822, 842, 530, 979 is 1
