Given numbers are 663, 660, 885, 550

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

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

Prime factors of 885 are 3 x 5 x 59

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 663, 660, 885, 550

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

Apply this formula for all numbers.

Step1:

LCM(663, 660) = 145860

GCD(663, 660) = ( 663 x 660 ) / 145860

= 663 / 660

= 663

Step2:

LCM(3, 885) = 885

GCD(3, 885) = ( 3 x 885 ) / 885

= 3 / 885

= 3

Step3:

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

= 3 / 550

= 3

So, Greatest Common Divisor of 663, 660, 885, 550 is 1
