Given numbers are 451, 117, 399, 663

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

Apply this formula for all numbers.

Step1:

LCM(451, 117) = 52767

GCD(451, 117) = ( 451 x 117 ) / 52767

= 451 / 117

= 451

Step2:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 451, 117, 399, 663 is 1
