GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 945) = 16065
GCD(255, 945) = ( 255 x 945 ) / 16065
= 255 / 945
= 255
Step2:
LCM(15, 903) = 4515
GCD(15, 903) = ( 15 x 903 ) / 4515
= 15 / 903
= 15
Step3:
LCM(3, 603) = 603
GCD(3, 603) = ( 3 x 603 ) / 603
= 3 / 603
= 3
So, Greatest Common Divisor of 255, 945, 903, 603 is 3
