The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 610 are 2 x 5 x 61

Prime factors of 489 are 3 x 163

Prime factors of 917 are 7 x 131

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

Given numbers are 215, 610, 489, 917

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

Apply this formula for all numbers.

Step1:

LCM(215, 610) = 26230

GCD(215, 610) = ( 215 x 610 ) / 26230

= 215 / 610

= 215

Step2:

LCM(5, 489) = 2445

GCD(5, 489) = ( 5 x 489 ) / 2445

= 5 / 489

= 5

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 215, 610, 489, 917 is 1
