Given numbers are 284, 383, 342, 155

The list of prime factors of all numbers are

Prime factors of 284 are 2 x 2 x 71

Prime factors of 383 are 383

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 155 are 5 x 31

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

Given numbers are 284, 383, 342, 155

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

Apply this formula for all numbers.

Step1:

LCM(284, 383) = 108772

GCD(284, 383) = ( 284 x 383 ) / 108772

= 284 / 383

= 284

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 284, 383, 342, 155 is 1
