Given numbers are 257, 780, 236, 515

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 236 are 2 x 2 x 59

Prime factors of 515 are 5 x 103

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

Given numbers are 257, 780, 236, 515

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

Apply this formula for all numbers.

Step1:

LCM(257, 780) = 200460

GCD(257, 780) = ( 257 x 780 ) / 200460

= 257 / 780

= 257

Step2:

LCM(1, 236) = 236

GCD(1, 236) = ( 1 x 236 ) / 236

= 1 / 236

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 257, 780, 236, 515 is 1
