Given numbers are 489, 247, 64, 244

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

Apply this formula for all numbers.

Step1:

LCM(489, 247) = 120783

GCD(489, 247) = ( 489 x 247 ) / 120783

= 489 / 247

= 489

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

Step3:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

So, Greatest Common Divisor of 489, 247, 64, 244 is 1
