Given numbers are 225, 729, 222, 215

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

Apply this formula for all numbers.

Step1:

LCM(225, 729) = 18225

GCD(225, 729) = ( 225 x 729 ) / 18225

= 225 / 729

= 225

Step2:

LCM(9, 222) = 666

GCD(9, 222) = ( 9 x 222 ) / 666

= 9 / 222

= 9

Step3:

LCM(3, 215) = 645

GCD(3, 215) = ( 3 x 215 ) / 645

= 3 / 215

= 3

So, Greatest Common Divisor of 225, 729, 222, 215 is 1
