Given numbers are 815, 644, 945, 593

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 593 are 593

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

Given numbers are 815, 644, 945, 593

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

Apply this formula for all numbers.

Step1:

LCM(815, 644) = 524860

GCD(815, 644) = ( 815 x 644 ) / 524860

= 815 / 644

= 815

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 593) = 593

GCD(1, 593) = ( 1 x 593 ) / 593

= 1 / 593

= 1

So, Greatest Common Divisor of 815, 644, 945, 593 is 1
