Given numbers are 445, 190, 590, 420

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

Apply this formula for all numbers.

Step1:

LCM(445, 190) = 16910

GCD(445, 190) = ( 445 x 190 ) / 16910

= 445 / 190

= 445

Step2:

LCM(5, 590) = 590

GCD(5, 590) = ( 5 x 590 ) / 590

= 5 / 590

= 5

Step3:

LCM(5, 420) = 420

GCD(5, 420) = ( 5 x 420 ) / 420

= 5 / 420

= 5

So, Greatest Common Divisor of 445, 190, 590, 420 is 5
