Given numbers are 221, 664, 118, 624

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 118 are 2 x 59

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 221, 664, 118, 624

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

Apply this formula for all numbers.

Step1:

LCM(221, 664) = 146744

GCD(221, 664) = ( 221 x 664 ) / 146744

= 221 / 664

= 221

Step2:

LCM(1, 118) = 118

GCD(1, 118) = ( 1 x 118 ) / 118

= 1 / 118

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 221, 664, 118, 624 is 1
