Given numbers are 984, 969, 438, 820

The list of prime factors of all numbers are

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

Prime factors of 969 are 3 x 17 x 19

Prime factors of 438 are 2 x 3 x 73

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 984, 969, 438, 820

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

Apply this formula for all numbers.

Step1:

LCM(984, 969) = 317832

GCD(984, 969) = ( 984 x 969 ) / 317832

= 984 / 969

= 984

Step2:

LCM(3, 438) = 438

GCD(3, 438) = ( 3 x 438 ) / 438

= 3 / 438

= 3

Step3:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

So, Greatest Common Divisor of 984, 969, 438, 820 is 1
