Given numbers are 447, 915, 606, 180

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

Apply this formula for all numbers.

Step1:

LCM(447, 915) = 136335

GCD(447, 915) = ( 447 x 915 ) / 136335

= 447 / 915

= 447

Step2:

LCM(3, 606) = 606

GCD(3, 606) = ( 3 x 606 ) / 606

= 3 / 606

= 3

Step3:

LCM(3, 180) = 180

GCD(3, 180) = ( 3 x 180 ) / 180

= 3 / 180

= 3

So, Greatest Common Divisor of 447, 915, 606, 180 is 3
