Given numbers are 258, 388, 989, 866

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

Apply this formula for all numbers.

Step1:

LCM(258, 388) = 50052

GCD(258, 388) = ( 258 x 388 ) / 50052

= 258 / 388

= 258

Step2:

LCM(2, 989) = 1978

GCD(2, 989) = ( 2 x 989 ) / 1978

= 2 / 989

= 2

Step3:

LCM(1, 866) = 866

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

= 1 / 866

= 1

So, Greatest Common Divisor of 258, 388, 989, 866 is 1
