Given numbers are 435, 205, 32, 309

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

Apply this formula for all numbers.

Step1:

LCM(435, 205) = 17835

GCD(435, 205) = ( 435 x 205 ) / 17835

= 435 / 205

= 435

Step2:

LCM(5, 32) = 160

GCD(5, 32) = ( 5 x 32 ) / 160

= 5 / 32

= 5

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 435, 205, 32, 309 is 1
