Given numbers are 285, 138, 245, 889

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

Apply this formula for all numbers.

Step1:

LCM(285, 138) = 13110

GCD(285, 138) = ( 285 x 138 ) / 13110

= 285 / 138

= 285

Step2:

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

= 3 / 245

= 3

Step3:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

So, Greatest Common Divisor of 285, 138, 245, 889 is 1
