Given numbers are 189, 852, 391, 435

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

Apply this formula for all numbers.

Step1:

LCM(189, 852) = 53676

GCD(189, 852) = ( 189 x 852 ) / 53676

= 189 / 852

= 189

Step2:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 189, 852, 391, 435 is 1
