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

Apply this formula for all numbers.

Step1:

LCM(624, 729) = 151632

GCD(624, 729) = ( 624 x 729 ) / 151632

= 624 / 729

= 624

Step2:

LCM(3, 906) = 906

GCD(3, 906) = ( 3 x 906 ) / 906

= 3 / 906

= 3

Step3:

LCM(3, 855) = 855

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

= 3 / 855

= 3

So, Greatest Common Divisor of 624, 729, 906, 855 is 3
