Given numbers are 397, 243, 515, 622

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

Apply this formula for all numbers.

Step1:

LCM(397, 243) = 96471

GCD(397, 243) = ( 397 x 243 ) / 96471

= 397 / 243

= 397

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

So, Greatest Common Divisor of 397, 243, 515, 622 is 1
