Given numbers are 284, 639, 669

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

Apply this formula for all numbers.

Step1:

LCM(284, 639) = 2556

GCD(284, 639) = ( 284 x 639 ) / 2556

= 284 / 639

= 284

Step2:

LCM(71, 669) = 47499

GCD(71, 669) = ( 71 x 669 ) / 47499

= 71 / 669

= 71

So, Greatest Common Divisor of 284, 639, 669 is 1
