Given numbers are 280, 478, 818, 711

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

Apply this formula for all numbers.

Step1:

LCM(280, 478) = 66920

GCD(280, 478) = ( 280 x 478 ) / 66920

= 280 / 478

= 280

Step2:

LCM(2, 818) = 818

GCD(2, 818) = ( 2 x 818 ) / 818

= 2 / 818

= 2

Step3:

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

= 2 / 711

= 2

So, Greatest Common Divisor of 280, 478, 818, 711 is 1
