Given numbers are 280, 205, 885, 821

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

Apply this formula for all numbers.

Step1:

LCM(280, 205) = 11480

GCD(280, 205) = ( 280 x 205 ) / 11480

= 280 / 205

= 280

Step2:

LCM(5, 885) = 885

GCD(5, 885) = ( 5 x 885 ) / 885

= 5 / 885

= 5

Step3:

LCM(5, 821) = 4105

GCD(5, 821) = ( 5 x 821 ) / 4105

= 5 / 821

= 5

So, Greatest Common Divisor of 280, 205, 885, 821 is 1
