Given numbers are 573, 780, 865, 393

The list of prime factors of all numbers are

Prime factors of 573 are 3 x 191

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 865 are 5 x 173

Prime factors of 393 are 3 x 131

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

Given numbers are 573, 780, 865, 393

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

Apply this formula for all numbers.

Step1:

LCM(573, 780) = 148980

GCD(573, 780) = ( 573 x 780 ) / 148980

= 573 / 780

= 573

Step2:

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

= 3 / 865

= 3

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 573, 780, 865, 393 is 1
