Given numbers are 669, 694, 621, 520

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

Apply this formula for all numbers.

Step1:

LCM(669, 694) = 464286

GCD(669, 694) = ( 669 x 694 ) / 464286

= 669 / 694

= 669

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 669, 694, 621, 520 is 1
