Given numbers are 517, 385, 23, 380

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

Apply this formula for all numbers.

Step1:

LCM(517, 385) = 18095

GCD(517, 385) = ( 517 x 385 ) / 18095

= 517 / 385

= 517

Step2:

LCM(11, 23) = 253

GCD(11, 23) = ( 11 x 23 ) / 253

= 11 / 23

= 11

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 517, 385, 23, 380 is 1
