Given numbers are 869, 393, 820, 982

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

Apply this formula for all numbers.

Step1:

LCM(869, 393) = 341517

GCD(869, 393) = ( 869 x 393 ) / 341517

= 869 / 393

= 869

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 982) = 982

GCD(1, 982) = ( 1 x 982 ) / 982

= 1 / 982

= 1

So, Greatest Common Divisor of 869, 393, 820, 982 is 1
