Given numbers are 623, 315, 986, 205

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

Apply this formula for all numbers.

Step1:

LCM(623, 315) = 28035

GCD(623, 315) = ( 623 x 315 ) / 28035

= 623 / 315

= 623

Step2:

LCM(7, 986) = 6902

GCD(7, 986) = ( 7 x 986 ) / 6902

= 7 / 986

= 7

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 623, 315, 986, 205 is 1
