Given numbers are 257, 534, 770, 640

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 534 are 2 x 3 x 89

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 257, 534, 770, 640

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

Apply this formula for all numbers.

Step1:

LCM(257, 534) = 137238

GCD(257, 534) = ( 257 x 534 ) / 137238

= 257 / 534

= 257

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 257, 534, 770, 640 is 1
