Given numbers are 705, 189, 435, 154

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

Apply this formula for all numbers.

Step1:

LCM(705, 189) = 44415

GCD(705, 189) = ( 705 x 189 ) / 44415

= 705 / 189

= 705

Step2:

LCM(3, 435) = 435

GCD(3, 435) = ( 3 x 435 ) / 435

= 3 / 435

= 3

Step3:

LCM(3, 154) = 462

GCD(3, 154) = ( 3 x 154 ) / 462

= 3 / 154

= 3

So, Greatest Common Divisor of 705, 189, 435, 154 is 1
