Given numbers are 213, 868, 391

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

Apply this formula for all numbers.

Step1:

LCM(213, 868) = 184884

GCD(213, 868) = ( 213 x 868 ) / 184884

= 213 / 868

= 213

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 213, 868, 391 is 1
