Given numbers are 239, 491, 861, 315

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

Apply this formula for all numbers.

Step1:

LCM(239, 491) = 117349

GCD(239, 491) = ( 239 x 491 ) / 117349

= 239 / 491

= 239

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 239, 491, 861, 315 is 1
