Given numbers are 309, 430, 332, 820

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

Apply this formula for all numbers.

Step1:

LCM(309, 430) = 132870

GCD(309, 430) = ( 309 x 430 ) / 132870

= 309 / 430

= 309

Step2:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 309, 430, 332, 820 is 1
