Given numbers are 445, 855, 668, 419

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

Apply this formula for all numbers.

Step1:

LCM(445, 855) = 76095

GCD(445, 855) = ( 445 x 855 ) / 76095

= 445 / 855

= 445

Step2:

LCM(5, 668) = 3340

GCD(5, 668) = ( 5 x 668 ) / 3340

= 5 / 668

= 5

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 445, 855, 668, 419 is 1
