Given numbers are 218, 489, 485, 660

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 489 are 3 x 163

Prime factors of 485 are 5 x 97

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 218, 489, 485, 660

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

Apply this formula for all numbers.

Step1:

LCM(218, 489) = 106602

GCD(218, 489) = ( 218 x 489 ) / 106602

= 218 / 489

= 218

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 218, 489, 485, 660 is 1
