Given numbers are 219, 438, 361, 445

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

Apply this formula for all numbers.

Step1:

LCM(219, 438) = 438

GCD(219, 438) = ( 219 x 438 ) / 438

= 219 / 438

= 219

Step2:

LCM(219, 361) = 79059

GCD(219, 361) = ( 219 x 361 ) / 79059

= 219 / 361

= 219

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 219, 438, 361, 445 is 1
