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

Apply this formula for all numbers.

Step1:

LCM(664, 778) = 258296

GCD(664, 778) = ( 664 x 778 ) / 258296

= 664 / 778

= 664

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

So, Greatest Common Divisor of 664, 778, 447 is 1
