Given numbers are 399, 657, 228, 631

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

Apply this formula for all numbers.

Step1:

LCM(399, 657) = 87381

GCD(399, 657) = ( 399 x 657 ) / 87381

= 399 / 657

= 399

Step2:

LCM(3, 228) = 228

GCD(3, 228) = ( 3 x 228 ) / 228

= 3 / 228

= 3

Step3:

LCM(3, 631) = 1893

GCD(3, 631) = ( 3 x 631 ) / 1893

= 3 / 631

= 3

So, Greatest Common Divisor of 399, 657, 228, 631 is 1
