Given numbers are 209, 665, 290, 444

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

Apply this formula for all numbers.

Step1:

LCM(209, 665) = 7315

GCD(209, 665) = ( 209 x 665 ) / 7315

= 209 / 665

= 209

Step2:

LCM(19, 290) = 5510

GCD(19, 290) = ( 19 x 290 ) / 5510

= 19 / 290

= 19

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 209, 665, 290, 444 is 1
