Given numbers are 423, 492, 349, 530

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

Apply this formula for all numbers.

Step1:

LCM(423, 492) = 69372

GCD(423, 492) = ( 423 x 492 ) / 69372

= 423 / 492

= 423

Step2:

LCM(3, 349) = 1047

GCD(3, 349) = ( 3 x 349 ) / 1047

= 3 / 349

= 3

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 423, 492, 349, 530 is 1
