Given numbers are 221, 585, 142, 451

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 585 are 3 x 3 x 5 x 13

Prime factors of 142 are 2 x 71

Prime factors of 451 are 11 x 41

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

Given numbers are 221, 585, 142, 451

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

Apply this formula for all numbers.

Step1:

LCM(221, 585) = 9945

GCD(221, 585) = ( 221 x 585 ) / 9945

= 221 / 585

= 221

Step2:

LCM(13, 142) = 1846

GCD(13, 142) = ( 13 x 142 ) / 1846

= 13 / 142

= 13

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 221, 585, 142, 451 is 1
