Given numbers are 257, 480, 695, 507

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 695 are 5 x 139

Prime factors of 507 are 3 x 13 x 13

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

Given numbers are 257, 480, 695, 507

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

Apply this formula for all numbers.

Step1:

LCM(257, 480) = 123360

GCD(257, 480) = ( 257 x 480 ) / 123360

= 257 / 480

= 257

Step2:

LCM(1, 695) = 695

GCD(1, 695) = ( 1 x 695 ) / 695

= 1 / 695

= 1

Step3:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

So, Greatest Common Divisor of 257, 480, 695, 507 is 1
