Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 978, 459, 990, 544

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

Apply this formula for all numbers.

Step1:

LCM(978, 459) = 149634

GCD(978, 459) = ( 978 x 459 ) / 149634

= 978 / 459

= 978

Step2:

LCM(3, 990) = 990

GCD(3, 990) = ( 3 x 990 ) / 990

= 3 / 990

= 3

Step3:

LCM(3, 544) = 1632

GCD(3, 544) = ( 3 x 544 ) / 1632

= 3 / 544

= 3

So, Greatest Common Divisor of 978, 459, 990, 544 is 1
