Given numbers are 280, 189, 411, 571

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

Apply this formula for all numbers.

Step1:

LCM(280, 189) = 7560

GCD(280, 189) = ( 280 x 189 ) / 7560

= 280 / 189

= 280

Step2:

LCM(7, 411) = 2877

GCD(7, 411) = ( 7 x 411 ) / 2877

= 7 / 411

= 7

Step3:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

So, Greatest Common Divisor of 280, 189, 411, 571 is 1
