Given numbers are 890, 399, 428, 866

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

Apply this formula for all numbers.

Step1:

LCM(890, 399) = 355110

GCD(890, 399) = ( 890 x 399 ) / 355110

= 890 / 399

= 890

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 890, 399, 428, 866 is 1
