Given numbers are 289, 238, 139, 660

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

Apply this formula for all numbers.

Step1:

LCM(289, 238) = 4046

GCD(289, 238) = ( 289 x 238 ) / 4046

= 289 / 238

= 289

Step2:

LCM(17, 139) = 2363

GCD(17, 139) = ( 17 x 139 ) / 2363

= 17 / 139

= 17

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 289, 238, 139, 660 is 1
