Given numbers are 215, 456, 238, 657

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 238 are 2 x 7 x 17

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 215, 456, 238, 657

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

Apply this formula for all numbers.

Step1:

LCM(215, 456) = 98040

GCD(215, 456) = ( 215 x 456 ) / 98040

= 215 / 456

= 215

Step2:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

Step3:

LCM(1, 657) = 657

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

= 1 / 657

= 1

So, Greatest Common Divisor of 215, 456, 238, 657 is 1
