Given numbers are 257, 740, 960, 905

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 905 are 5 x 181

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

Given numbers are 257, 740, 960, 905

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

Apply this formula for all numbers.

Step1:

LCM(257, 740) = 190180

GCD(257, 740) = ( 257 x 740 ) / 190180

= 257 / 740

= 257

Step2:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 257, 740, 960, 905 is 1
