Given numbers are 663, 411, 408, 617

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

Apply this formula for all numbers.

Step1:

LCM(663, 411) = 90831

GCD(663, 411) = ( 663 x 411 ) / 90831

= 663 / 411

= 663

Step2:

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

= 3 / 408

= 3

Step3:

LCM(3, 617) = 1851

GCD(3, 617) = ( 3 x 617 ) / 1851

= 3 / 617

= 3

So, Greatest Common Divisor of 663, 411, 408, 617 is 1
