Given numbers are 663, 660, 455, 300

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 455 are 5 x 7 x 13

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

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

Given numbers are 663, 660, 455, 300

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, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 300) = 300

GCD(1, 300) = ( 1 x 300 ) / 300

= 1 / 300

= 1

So, Greatest Common Divisor of 663, 660, 455, 300 is 1
