Given numbers are 668, 480, 396, 445

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

Apply this formula for all numbers.

Step1:

LCM(668, 480) = 80160

GCD(668, 480) = ( 668 x 480 ) / 80160

= 668 / 480

= 668

Step2:

LCM(4, 396) = 396

GCD(4, 396) = ( 4 x 396 ) / 396

= 4 / 396

= 4

Step3:

LCM(4, 445) = 1780

GCD(4, 445) = ( 4 x 445 ) / 1780

= 4 / 445

= 4

So, Greatest Common Divisor of 668, 480, 396, 445 is 1
