Given numbers are 257, 486, 820, 540

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 257, 486, 820, 540

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

Apply this formula for all numbers.

Step1:

LCM(257, 486) = 124902

GCD(257, 486) = ( 257 x 486 ) / 124902

= 257 / 486

= 257

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 257, 486, 820, 540 is 1
