Given numbers are 258, 897, 986, 643

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

Apply this formula for all numbers.

Step1:

LCM(258, 897) = 77142

GCD(258, 897) = ( 258 x 897 ) / 77142

= 258 / 897

= 258

Step2:

LCM(3, 986) = 2958

GCD(3, 986) = ( 3 x 986 ) / 2958

= 3 / 986

= 3

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 258, 897, 986, 643 is 1
