Given numbers are 669, 174, 815, 438

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

Apply this formula for all numbers.

Step1:

LCM(669, 174) = 38802

GCD(669, 174) = ( 669 x 174 ) / 38802

= 669 / 174

= 669

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 669, 174, 815, 438 is 1
