Given numbers are 158, 308, 457, 458

The list of prime factors of all numbers are

Prime factors of 158 are 2 x 79

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 457 are 457

Prime factors of 458 are 2 x 229

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

Given numbers are 158, 308, 457, 458

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

Apply this formula for all numbers.

Step1:

LCM(158, 308) = 24332

GCD(158, 308) = ( 158 x 308 ) / 24332

= 158 / 308

= 158

Step2:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 158, 308, 457, 458 is 1
