Given numbers are 861, 582, 787, 321

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

Apply this formula for all numbers.

Step1:

LCM(861, 582) = 167034

GCD(861, 582) = ( 861 x 582 ) / 167034

= 861 / 582

= 861

Step2:

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

= 3 / 787

= 3

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 861, 582, 787, 321 is 1
