Given numbers are 978, 460, 355, 580

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 355 are 5 x 71

Prime factors of 580 are 2 x 2 x 5 x 29

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

Given numbers are 978, 460, 355, 580

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

Apply this formula for all numbers.

Step1:

LCM(978, 460) = 224940

GCD(978, 460) = ( 978 x 460 ) / 224940

= 978 / 460

= 978

Step2:

LCM(2, 355) = 710

GCD(2, 355) = ( 2 x 355 ) / 710

= 2 / 355

= 2

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 978, 460, 355, 580 is 1
