Given numbers are 603, 318, 156, 855

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

Apply this formula for all numbers.

Step1:

LCM(603, 318) = 63918

GCD(603, 318) = ( 603 x 318 ) / 63918

= 603 / 318

= 603

Step2:

LCM(3, 156) = 156

GCD(3, 156) = ( 3 x 156 ) / 156

= 3 / 156

= 3

Step3:

LCM(3, 855) = 855

GCD(3, 855) = ( 3 x 855 ) / 855

= 3 / 855

= 3

So, Greatest Common Divisor of 603, 318, 156, 855 is 3
