Given numbers are 805, 196, 243, 343

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

Apply this formula for all numbers.

Step1:

LCM(805, 196) = 22540

GCD(805, 196) = ( 805 x 196 ) / 22540

= 805 / 196

= 805

Step2:

LCM(7, 243) = 1701

GCD(7, 243) = ( 7 x 243 ) / 1701

= 7 / 243

= 7

Step3:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

So, Greatest Common Divisor of 805, 196, 243, 343 is 1
