Given numbers are 409, 545, 330, 818

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

Apply this formula for all numbers.

Step1:

LCM(409, 545) = 222905

GCD(409, 545) = ( 409 x 545 ) / 222905

= 409 / 545

= 409

Step2:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 409, 545, 330, 818 is 1
