Given numbers are 158, 320, 227, 221

The list of prime factors of all numbers are

Prime factors of 158 are 2 x 79

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 227 are 227

Prime factors of 221 are 13 x 17

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

Given numbers are 158, 320, 227, 221

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

Apply this formula for all numbers.

Step1:

LCM(158, 320) = 25280

GCD(158, 320) = ( 158 x 320 ) / 25280

= 158 / 320

= 158

Step2:

LCM(2, 227) = 454

GCD(2, 227) = ( 2 x 227 ) / 454

= 2 / 227

= 2

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 158, 320, 227, 221 is 1
