Given numbers are 218, 392, 578, 871

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

Apply this formula for all numbers.

Step1:

LCM(218, 392) = 42728

GCD(218, 392) = ( 218 x 392 ) / 42728

= 218 / 392

= 218

Step2:

LCM(2, 578) = 578

GCD(2, 578) = ( 2 x 578 ) / 578

= 2 / 578

= 2

Step3:

LCM(2, 871) = 1742

GCD(2, 871) = ( 2 x 871 ) / 1742

= 2 / 871

= 2

So, Greatest Common Divisor of 218, 392, 578, 871 is 1
