Given numbers are 164, 661, 396, 225

The list of prime factors of all numbers are

Prime factors of 164 are 2 x 2 x 41

Prime factors of 661 are 661

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 225 are 3 x 3 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 164, 661, 396, 225

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

Apply this formula for all numbers.

Step1:

LCM(164, 661) = 108404

GCD(164, 661) = ( 164 x 661 ) / 108404

= 164 / 661

= 164

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 225) = 225

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

= 1 / 225

= 1

So, Greatest Common Divisor of 164, 661, 396, 225 is 1
