Given numbers are 388, 820, 805, 310

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

Apply this formula for all numbers.

Step1:

LCM(388, 820) = 79540

GCD(388, 820) = ( 388 x 820 ) / 79540

= 388 / 820

= 388

Step2:

LCM(4, 805) = 3220

GCD(4, 805) = ( 4 x 805 ) / 3220

= 4 / 805

= 4

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 388, 820, 805, 310 is 1
