Given numbers are 162, 861, 223, 225

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

Apply this formula for all numbers.

Step1:

LCM(162, 861) = 46494

GCD(162, 861) = ( 162 x 861 ) / 46494

= 162 / 861

= 162

Step2:

LCM(3, 223) = 669

GCD(3, 223) = ( 3 x 223 ) / 669

= 3 / 223

= 3

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 162, 861, 223, 225 is 1
