Given numbers are 664, 856, 413, 578

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

Apply this formula for all numbers.

Step1:

LCM(664, 856) = 71048

GCD(664, 856) = ( 664 x 856 ) / 71048

= 664 / 856

= 664

Step2:

LCM(8, 413) = 3304

GCD(8, 413) = ( 8 x 413 ) / 3304

= 8 / 413

= 8

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 664, 856, 413, 578 is 1
