Given numbers are 855, 828, 666, 159

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

Apply this formula for all numbers.

Step1:

LCM(855, 828) = 78660

GCD(855, 828) = ( 855 x 828 ) / 78660

= 855 / 828

= 855

Step2:

LCM(9, 666) = 666

GCD(9, 666) = ( 9 x 666 ) / 666

= 9 / 666

= 9

Step3:

LCM(9, 159) = 477

GCD(9, 159) = ( 9 x 159 ) / 477

= 9 / 159

= 9

So, Greatest Common Divisor of 855, 828, 666, 159 is 3
