Given numbers are 205, 943, 986, 980

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

Apply this formula for all numbers.

Step1:

LCM(205, 943) = 4715

GCD(205, 943) = ( 205 x 943 ) / 4715

= 205 / 943

= 205

Step2:

LCM(41, 986) = 40426

GCD(41, 986) = ( 41 x 986 ) / 40426

= 41 / 986

= 41

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 205, 943, 986, 980 is 1
