Given numbers are 338, 889, 455, 245

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

Apply this formula for all numbers.

Step1:

LCM(338, 889) = 300482

GCD(338, 889) = ( 338 x 889 ) / 300482

= 338 / 889

= 338

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 338, 889, 455, 245 is 1
