Given numbers are 205, 646, 755, 995

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

Apply this formula for all numbers.

Step1:

LCM(205, 646) = 132430

GCD(205, 646) = ( 205 x 646 ) / 132430

= 205 / 646

= 205

Step2:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

Step3:

LCM(1, 995) = 995

GCD(1, 995) = ( 1 x 995 ) / 995

= 1 / 995

= 1

So, Greatest Common Divisor of 205, 646, 755, 995 is 1
