Given numbers are 663, 206, 648, 220

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 206 are 2 x 103

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 663, 206, 648, 220

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

Apply this formula for all numbers.

Step1:

LCM(663, 206) = 136578

GCD(663, 206) = ( 663 x 206 ) / 136578

= 663 / 206

= 663

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 663, 206, 648, 220 is 1
