Given numbers are 664, 678, 411, 561

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

Apply this formula for all numbers.

Step1:

LCM(664, 678) = 225096

GCD(664, 678) = ( 664 x 678 ) / 225096

= 664 / 678

= 664

Step2:

LCM(2, 411) = 822

GCD(2, 411) = ( 2 x 411 ) / 822

= 2 / 411

= 2

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 664, 678, 411, 561 is 1
