Given numbers are 669, 170, 381

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

Apply this formula for all numbers.

Step1:

LCM(669, 170) = 113730

GCD(669, 170) = ( 669 x 170 ) / 113730

= 669 / 170

= 669

Step2:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 669, 170, 381 is 1
