Given numbers are 289, 357, 805, 124

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

Apply this formula for all numbers.

Step1:

LCM(289, 357) = 6069

GCD(289, 357) = ( 289 x 357 ) / 6069

= 289 / 357

= 289

Step2:

LCM(17, 805) = 13685

GCD(17, 805) = ( 17 x 805 ) / 13685

= 17 / 805

= 17

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 289, 357, 805, 124 is 1
