Given numbers are 489, 970, 180, 100

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 970 are 2 x 5 x 97

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 100 are 2 x 2 x 5 x 5

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

Given numbers are 489, 970, 180, 100

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

Apply this formula for all numbers.

Step1:

LCM(489, 970) = 474330

GCD(489, 970) = ( 489 x 970 ) / 474330

= 489 / 970

= 489

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

So, Greatest Common Divisor of 489, 970, 180, 100 is 1
