Given numbers are 669, 470, 865, 400

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

Apply this formula for all numbers.

Step1:

LCM(669, 470) = 314430

GCD(669, 470) = ( 669 x 470 ) / 314430

= 669 / 470

= 669

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 669, 470, 865, 400 is 1
