Given numbers are 423, 165, 378, 577

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

Apply this formula for all numbers.

Step1:

LCM(423, 165) = 23265

GCD(423, 165) = ( 423 x 165 ) / 23265

= 423 / 165

= 423

Step2:

LCM(3, 378) = 378

GCD(3, 378) = ( 3 x 378 ) / 378

= 3 / 378

= 3

Step3:

LCM(3, 577) = 1731

GCD(3, 577) = ( 3 x 577 ) / 1731

= 3 / 577

= 3

So, Greatest Common Divisor of 423, 165, 378, 577 is 1
