Given numbers are 984, 639, 245, 442

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 639 are 3 x 3 x 71

Prime factors of 245 are 5 x 7 x 7

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 984, 639, 245, 442

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

Apply this formula for all numbers.

Step1:

LCM(984, 639) = 209592

GCD(984, 639) = ( 984 x 639 ) / 209592

= 984 / 639

= 984

Step2:

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

= 3 / 245

= 3

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 984, 639, 245, 442 is 1
