Given numbers are 392, 105, 430, 805

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

Apply this formula for all numbers.

Step1:

LCM(392, 105) = 5880

GCD(392, 105) = ( 392 x 105 ) / 5880

= 392 / 105

= 392

Step2:

LCM(7, 430) = 3010

GCD(7, 430) = ( 7 x 430 ) / 3010

= 7 / 430

= 7

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 392, 105, 430, 805 is 1
