Given numbers are 663, 819, 881, 658

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

Apply this formula for all numbers.

Step1:

LCM(663, 819) = 13923

GCD(663, 819) = ( 663 x 819 ) / 13923

= 663 / 819

= 663

Step2:

LCM(39, 881) = 34359

GCD(39, 881) = ( 39 x 881 ) / 34359

= 39 / 881

= 39

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 663, 819, 881, 658 is 1
