Given numbers are 445, 474, 391, 779

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

Apply this formula for all numbers.

Step1:

LCM(445, 474) = 210930

GCD(445, 474) = ( 445 x 474 ) / 210930

= 445 / 474

= 445

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

So, Greatest Common Divisor of 445, 474, 391, 779 is 1
