Given numbers are 928, 690, 102, 489

The list of prime factors of all numbers are

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 102 are 2 x 3 x 17

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 928, 690, 102, 489

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

Apply this formula for all numbers.

Step1:

LCM(928, 690) = 320160

GCD(928, 690) = ( 928 x 690 ) / 320160

= 928 / 690

= 928

Step2:

LCM(2, 102) = 102

GCD(2, 102) = ( 2 x 102 ) / 102

= 2 / 102

= 2

Step3:

LCM(2, 489) = 978

GCD(2, 489) = ( 2 x 489 ) / 978

= 2 / 489

= 2

So, Greatest Common Divisor of 928, 690, 102, 489 is 1
