Given numbers are 663, 398, 838, 587

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

Apply this formula for all numbers.

Step1:

LCM(663, 398) = 263874

GCD(663, 398) = ( 663 x 398 ) / 263874

= 663 / 398

= 663

Step2:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

Step3:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

So, Greatest Common Divisor of 663, 398, 838, 587 is 1
