Given numbers are 978, 187, 478, 810

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 187 are 11 x 17

Prime factors of 478 are 2 x 239

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 978, 187, 478, 810

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

Apply this formula for all numbers.

Step1:

LCM(978, 187) = 182886

GCD(978, 187) = ( 978 x 187 ) / 182886

= 978 / 187

= 978

Step2:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 978, 187, 478, 810 is 1
