Given numbers are 321, 981, 457, 862

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

Apply this formula for all numbers.

Step1:

LCM(321, 981) = 104967

GCD(321, 981) = ( 321 x 981 ) / 104967

= 321 / 981

= 321

Step2:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

Step3:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

So, Greatest Common Divisor of 321, 981, 457, 862 is 1
