Given numbers are 189, 868, 931, 205

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

Apply this formula for all numbers.

Step1:

LCM(189, 868) = 23436

GCD(189, 868) = ( 189 x 868 ) / 23436

= 189 / 868

= 189

Step2:

LCM(7, 931) = 931

GCD(7, 931) = ( 7 x 931 ) / 931

= 7 / 931

= 7

Step3:

LCM(7, 205) = 1435

GCD(7, 205) = ( 7 x 205 ) / 1435

= 7 / 205

= 7

So, Greatest Common Divisor of 189, 868, 931, 205 is 1
