Given numbers are 219, 489, 360, 640

The list of prime factors of all numbers are

Prime factors of 219 are 3 x 73

Prime factors of 489 are 3 x 163

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 219, 489, 360, 640

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

Apply this formula for all numbers.

Step1:

LCM(219, 489) = 35697

GCD(219, 489) = ( 219 x 489 ) / 35697

= 219 / 489

= 219

Step2:

LCM(3, 360) = 360

GCD(3, 360) = ( 3 x 360 ) / 360

= 3 / 360

= 3

Step3:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

So, Greatest Common Divisor of 219, 489, 360, 640 is 1
