Given numbers are 865, 580, 63, 345

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

Apply this formula for all numbers.

Step1:

LCM(865, 580) = 100340

GCD(865, 580) = ( 865 x 580 ) / 100340

= 865 / 580

= 865

Step2:

LCM(5, 63) = 315

GCD(5, 63) = ( 5 x 63 ) / 315

= 5 / 63

= 5

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 865, 580, 63, 345 is 1
