Given numbers are 815, 342, 436, 144

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 436 are 2 x 2 x 109

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 815, 342, 436, 144

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

Apply this formula for all numbers.

Step1:

LCM(815, 342) = 278730

GCD(815, 342) = ( 815 x 342 ) / 278730

= 815 / 342

= 815

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 815, 342, 436, 144 is 1
