Given numbers are 225, 243, 823, 745

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

Apply this formula for all numbers.

Step1:

LCM(225, 243) = 6075

GCD(225, 243) = ( 225 x 243 ) / 6075

= 225 / 243

= 225

Step2:

LCM(9, 823) = 7407

GCD(9, 823) = ( 9 x 823 ) / 7407

= 9 / 823

= 9

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 225, 243, 823, 745 is 1
