Given numbers are 210, 822, 903, 678

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

Apply this formula for all numbers.

Step1:

LCM(210, 822) = 28770

GCD(210, 822) = ( 210 x 822 ) / 28770

= 210 / 822

= 210

Step2:

LCM(6, 903) = 1806

GCD(6, 903) = ( 6 x 903 ) / 1806

= 6 / 903

= 6

Step3:

LCM(3, 678) = 678

GCD(3, 678) = ( 3 x 678 ) / 678

= 3 / 678

= 3

So, Greatest Common Divisor of 210, 822, 903, 678 is 3
