Given numbers are 815, 603, 440, 434

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 603 are 3 x 3 x 67

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 815, 603, 440, 434

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

Apply this formula for all numbers.

Step1:

LCM(815, 603) = 491445

GCD(815, 603) = ( 815 x 603 ) / 491445

= 815 / 603

= 815

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 815, 603, 440, 434 is 1
