Given numbers are 173, 225, 417, 820

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

Apply this formula for all numbers.

Step1:

LCM(173, 225) = 38925

GCD(173, 225) = ( 173 x 225 ) / 38925

= 173 / 225

= 173

Step2:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 173, 225, 417, 820 is 1
