Given numbers are 851, 575, 863, 393

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

Apply this formula for all numbers.

Step1:

LCM(851, 575) = 21275

GCD(851, 575) = ( 851 x 575 ) / 21275

= 851 / 575

= 851

Step2:

LCM(23, 863) = 19849

GCD(23, 863) = ( 23 x 863 ) / 19849

= 23 / 863

= 23

Step3:

LCM(1, 393) = 393

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

= 1 / 393

= 1

So, Greatest Common Divisor of 851, 575, 863, 393 is 1
