Given numbers are 411, 165, 64, 685

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

Apply this formula for all numbers.

Step1:

LCM(411, 165) = 22605

GCD(411, 165) = ( 411 x 165 ) / 22605

= 411 / 165

= 411

Step2:

LCM(3, 64) = 192

GCD(3, 64) = ( 3 x 64 ) / 192

= 3 / 64

= 3

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 411, 165, 64, 685 is 1
