Given numbers are 417, 639, 326, 208

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

Apply this formula for all numbers.

Step1:

LCM(417, 639) = 88821

GCD(417, 639) = ( 417 x 639 ) / 88821

= 417 / 639

= 417

Step2:

LCM(3, 326) = 978

GCD(3, 326) = ( 3 x 326 ) / 978

= 3 / 326

= 3

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 417, 639, 326, 208 is 1
