Given numbers are 865, 265, 419, 320

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

Apply this formula for all numbers.

Step1:

LCM(865, 265) = 45845

GCD(865, 265) = ( 865 x 265 ) / 45845

= 865 / 265

= 865

Step2:

LCM(5, 419) = 2095

GCD(5, 419) = ( 5 x 419 ) / 2095

= 5 / 419

= 5

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 865, 265, 419, 320 is 1
