Given numbers are 400, 781, 908, 257

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 781 are 11 x 71

Prime factors of 908 are 2 x 2 x 227

Prime factors of 257 are 257

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

Given numbers are 400, 781, 908, 257

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

Apply this formula for all numbers.

Step1:

LCM(400, 781) = 312400

GCD(400, 781) = ( 400 x 781 ) / 312400

= 400 / 781

= 400

Step2:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 400, 781, 908, 257 is 1
