Given numbers are 819, 438, 453, 523

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

Apply this formula for all numbers.

Step1:

LCM(819, 438) = 119574

GCD(819, 438) = ( 819 x 438 ) / 119574

= 819 / 438

= 819

Step2:

LCM(3, 453) = 453

GCD(3, 453) = ( 3 x 453 ) / 453

= 3 / 453

= 3

Step3:

LCM(3, 523) = 1569

GCD(3, 523) = ( 3 x 523 ) / 1569

= 3 / 523

= 3

So, Greatest Common Divisor of 819, 438, 453, 523 is 1
