Given numbers are 581, 145, 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(581, 145) = 84245

GCD(581, 145) = ( 581 x 145 ) / 84245

= 581 / 145

= 581

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 393) = 393

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

= 1 / 393

= 1

So, Greatest Common Divisor of 581, 145, 865, 393 is 1
