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

Apply this formula for all numbers.

Step1:

LCM(177, 531) = 531

GCD(177, 531) = ( 177 x 531 ) / 531

= 177 / 531

= 177

Step2:

LCM(177, 249) = 14691

GCD(177, 249) = ( 177 x 249 ) / 14691

= 177 / 249

= 177

Step3:

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

= 3 / 408

= 3

So, Greatest Common Divisor of 177, 531, 249, 408 is 3
