Given numbers are 280, 203, 872, 279

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

Apply this formula for all numbers.

Step1:

LCM(280, 203) = 8120

GCD(280, 203) = ( 280 x 203 ) / 8120

= 280 / 203

= 280

Step2:

LCM(7, 872) = 6104

GCD(7, 872) = ( 7 x 872 ) / 6104

= 7 / 872

= 7

Step3:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

So, Greatest Common Divisor of 280, 203, 872, 279 is 1
