Given numbers are 997, 643, 415, 430

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

Apply this formula for all numbers.

Step1:

LCM(997, 643) = 641071

GCD(997, 643) = ( 997 x 643 ) / 641071

= 997 / 643

= 997

Step2:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 997, 643, 415, 430 is 1
