Given numbers are 423, 543, 547, 813

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

Apply this formula for all numbers.

Step1:

LCM(423, 543) = 76563

GCD(423, 543) = ( 423 x 543 ) / 76563

= 423 / 543

= 423

Step2:

LCM(3, 547) = 1641

GCD(3, 547) = ( 3 x 547 ) / 1641

= 3 / 547

= 3

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 423, 543, 547, 813 is 1
