Given numbers are 669, 114, 89, 644

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

Apply this formula for all numbers.

Step1:

LCM(669, 114) = 25422

GCD(669, 114) = ( 669 x 114 ) / 25422

= 669 / 114

= 669

Step2:

LCM(3, 89) = 267

GCD(3, 89) = ( 3 x 89 ) / 267

= 3 / 89

= 3

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 669, 114, 89, 644 is 1
