Given numbers are 217, 868, 20, 581

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

Apply this formula for all numbers.

Step1:

LCM(217, 868) = 868

GCD(217, 868) = ( 217 x 868 ) / 868

= 217 / 868

= 217

Step2:

LCM(217, 20) = 4340

GCD(217, 20) = ( 217 x 20 ) / 4340

= 217 / 20

= 217

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 217, 868, 20, 581 is 1
