Given numbers are 663, 949, 417, 340

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

Apply this formula for all numbers.

Step1:

LCM(663, 949) = 48399

GCD(663, 949) = ( 663 x 949 ) / 48399

= 663 / 949

= 663

Step2:

LCM(13, 417) = 5421

GCD(13, 417) = ( 13 x 417 ) / 5421

= 13 / 417

= 13

Step3:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

So, Greatest Common Divisor of 663, 949, 417, 340 is 1
