Given numbers are 189, 805, 152, 258

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

Apply this formula for all numbers.

Step1:

LCM(189, 805) = 21735

GCD(189, 805) = ( 189 x 805 ) / 21735

= 189 / 805

= 189

Step2:

LCM(7, 152) = 1064

GCD(7, 152) = ( 7 x 152 ) / 1064

= 7 / 152

= 7

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 189, 805, 152, 258 is 1
