Given numbers are 381, 782, 396, 857

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 782 are 2 x 17 x 23

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 857 are 857

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

Given numbers are 381, 782, 396, 857

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

Apply this formula for all numbers.

Step1:

LCM(381, 782) = 297942

GCD(381, 782) = ( 381 x 782 ) / 297942

= 381 / 782

= 381

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 381, 782, 396, 857 is 1
