Given numbers are 189, 645, 136, 705

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

Apply this formula for all numbers.

Step1:

LCM(189, 645) = 40635

GCD(189, 645) = ( 189 x 645 ) / 40635

= 189 / 645

= 189

Step2:

LCM(3, 136) = 408

GCD(3, 136) = ( 3 x 136 ) / 408

= 3 / 136

= 3

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 189, 645, 136, 705 is 1
