Given numbers are 861, 343, 205, 263

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

Apply this formula for all numbers.

Step1:

LCM(861, 343) = 42189

GCD(861, 343) = ( 861 x 343 ) / 42189

= 861 / 343

= 861

Step2:

LCM(7, 205) = 1435

GCD(7, 205) = ( 7 x 205 ) / 1435

= 7 / 205

= 7

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 861, 343, 205, 263 is 1
