Given numbers are 478, 650, 257, 706

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 257 are 257

Prime factors of 706 are 2 x 353

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

Given numbers are 478, 650, 257, 706

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

Apply this formula for all numbers.

Step1:

LCM(478, 650) = 155350

GCD(478, 650) = ( 478 x 650 ) / 155350

= 478 / 650

= 478

Step2:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

Step3:

LCM(1, 706) = 706

GCD(1, 706) = ( 1 x 706 ) / 706

= 1 / 706

= 1

So, Greatest Common Divisor of 478, 650, 257, 706 is 1
