Given numbers are 865, 455, 580, 839

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

Apply this formula for all numbers.

Step1:

LCM(865, 455) = 78715

GCD(865, 455) = ( 865 x 455 ) / 78715

= 865 / 455

= 865

Step2:

LCM(5, 580) = 580

GCD(5, 580) = ( 5 x 580 ) / 580

= 5 / 580

= 5

Step3:

LCM(5, 839) = 4195

GCD(5, 839) = ( 5 x 839 ) / 4195

= 5 / 839

= 5

So, Greatest Common Divisor of 865, 455, 580, 839 is 1
