Given numbers are 162, 138, 186, 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, 138) = 3726

GCD(162, 138) = ( 162 x 138 ) / 3726

= 162 / 138

= 162

Step2:

LCM(6, 186) = 186

GCD(6, 186) = ( 6 x 186 ) / 186

= 6 / 186

= 6

Step3:

LCM(6, 225) = 450

GCD(6, 225) = ( 6 x 225 ) / 450

= 6 / 225

= 6

So, Greatest Common Divisor of 162, 138, 186, 225 is 3
