Given numbers are 803, 435, 145, 815

The list of prime factors of all numbers are

Prime factors of 803 are 11 x 73

Prime factors of 435 are 3 x 5 x 29

Prime factors of 145 are 5 x 29

Prime factors of 815 are 5 x 163

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

Given numbers are 803, 435, 145, 815

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

Apply this formula for all numbers.

Step1:

LCM(803, 435) = 349305

GCD(803, 435) = ( 803 x 435 ) / 349305

= 803 / 435

= 803

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 803, 435, 145, 815 is 1
