Given numbers are 770, 460, 545, 257

The list of prime factors of all numbers are

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

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 545 are 5 x 109

Prime factors of 257 are 257

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

Given numbers are 770, 460, 545, 257

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

Apply this formula for all numbers.

Step1:

LCM(770, 460) = 35420

GCD(770, 460) = ( 770 x 460 ) / 35420

= 770 / 460

= 770

Step2:

LCM(10, 545) = 1090

GCD(10, 545) = ( 10 x 545 ) / 1090

= 10 / 545

= 10

Step3:

LCM(5, 257) = 1285

GCD(5, 257) = ( 5 x 257 ) / 1285

= 5 / 257

= 5

So, Greatest Common Divisor of 770, 460, 545, 257 is 1
