Given numbers are 213, 903, 855, 630

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

Apply this formula for all numbers.

Step1:

LCM(213, 903) = 64113

GCD(213, 903) = ( 213 x 903 ) / 64113

= 213 / 903

= 213

Step2:

LCM(3, 855) = 855

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

= 3 / 855

= 3

Step3:

LCM(3, 630) = 630

GCD(3, 630) = ( 3 x 630 ) / 630

= 3 / 630

= 3

So, Greatest Common Divisor of 213, 903, 855, 630 is 3
