Given numbers are 253, 147, 243, 657

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 147 are 3 x 7 x 7

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 253, 147, 243, 657

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

Apply this formula for all numbers.

Step1:

LCM(253, 147) = 37191

GCD(253, 147) = ( 253 x 147 ) / 37191

= 253 / 147

= 253

Step2:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 253, 147, 243, 657 is 1
