Given numbers are 820, 343, 395, 190

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

Apply this formula for all numbers.

Step1:

LCM(820, 343) = 281260

GCD(820, 343) = ( 820 x 343 ) / 281260

= 820 / 343

= 820

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

Step3:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 820, 343, 395, 190 is 1
