Given numbers are 275, 621, 395

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

Apply this formula for all numbers.

Step1:

LCM(275, 621) = 170775

GCD(275, 621) = ( 275 x 621 ) / 170775

= 275 / 621

= 275

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 275, 621, 395 is 1
