Given numbers are 785, 775, 320, 393

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

Apply this formula for all numbers.

Step1:

LCM(785, 775) = 121675

GCD(785, 775) = ( 785 x 775 ) / 121675

= 785 / 775

= 785

Step2:

LCM(5, 320) = 320

GCD(5, 320) = ( 5 x 320 ) / 320

= 5 / 320

= 5

Step3:

LCM(5, 393) = 1965

GCD(5, 393) = ( 5 x 393 ) / 1965

= 5 / 393

= 5

So, Greatest Common Divisor of 785, 775, 320, 393 is 1
