Given numbers are 945, 430, 681, 489

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 430 are 2 x 5 x 43

Prime factors of 681 are 3 x 227

Prime factors of 489 are 3 x 163

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

Given numbers are 945, 430, 681, 489

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

Apply this formula for all numbers.

Step1:

LCM(945, 430) = 81270

GCD(945, 430) = ( 945 x 430 ) / 81270

= 945 / 430

= 945

Step2:

LCM(5, 681) = 3405

GCD(5, 681) = ( 5 x 681 ) / 3405

= 5 / 681

= 5

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 945, 430, 681, 489 is 1
