Given numbers are 571, 921, 640, 259

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

Apply this formula for all numbers.

Step1:

LCM(571, 921) = 525891

GCD(571, 921) = ( 571 x 921 ) / 525891

= 571 / 921

= 571

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

So, Greatest Common Divisor of 571, 921, 640, 259 is 1
