Given numbers are 978, 505, 378, 312

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 505 are 5 x 101

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 978, 505, 378, 312

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

Apply this formula for all numbers.

Step1:

LCM(978, 505) = 493890

GCD(978, 505) = ( 978 x 505 ) / 493890

= 978 / 505

= 978

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 978, 505, 378, 312 is 1
