Given numbers are 143, 465, 221, 168

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 465 are 3 x 5 x 31

Prime factors of 221 are 13 x 17

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 143, 465, 221, 168

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

Apply this formula for all numbers.

Step1:

LCM(143, 465) = 66495

GCD(143, 465) = ( 143 x 465 ) / 66495

= 143 / 465

= 143

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 143, 465, 221, 168 is 1
