Given numbers are 485, 576, 840, 978

The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 485, 576, 840, 978

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

Apply this formula for all numbers.

Step1:

LCM(485, 576) = 279360

GCD(485, 576) = ( 485 x 576 ) / 279360

= 485 / 576

= 485

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 485, 576, 840, 978 is 1
