Given numbers are 205, 685, 436, 964

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

Apply this formula for all numbers.

Step1:

LCM(205, 685) = 28085

GCD(205, 685) = ( 205 x 685 ) / 28085

= 205 / 685

= 205

Step2:

LCM(5, 436) = 2180

GCD(5, 436) = ( 5 x 436 ) / 2180

= 5 / 436

= 5

Step3:

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

= 1 / 964

= 1

So, Greatest Common Divisor of 205, 685, 436, 964 is 1
