Given numbers are 446, 640, 885, 489

The list of prime factors of all numbers are

Prime factors of 446 are 2 x 223

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

Prime factors of 885 are 3 x 5 x 59

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 446, 640, 885, 489

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

Apply this formula for all numbers.

Step1:

LCM(446, 640) = 142720

GCD(446, 640) = ( 446 x 640 ) / 142720

= 446 / 640

= 446

Step2:

LCM(2, 885) = 1770

GCD(2, 885) = ( 2 x 885 ) / 1770

= 2 / 885

= 2

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 446, 640, 885, 489 is 1
