Given numbers are 716, 454, 243, 643

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

Apply this formula for all numbers.

Step1:

LCM(716, 454) = 162532

GCD(716, 454) = ( 716 x 454 ) / 162532

= 716 / 454

= 716

Step2:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 716, 454, 243, 643 is 1
