Given numbers are 257, 450, 91, 388

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 91 are 7 x 13

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 257, 450, 91, 388

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

Apply this formula for all numbers.

Step1:

LCM(257, 450) = 115650

GCD(257, 450) = ( 257 x 450 ) / 115650

= 257 / 450

= 257

Step2:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 257, 450, 91, 388 is 1
