Given numbers are 381, 419, 840, 769

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 419 are 419

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 769 are 769

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

Given numbers are 381, 419, 840, 769

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

Apply this formula for all numbers.

Step1:

LCM(381, 419) = 159639

GCD(381, 419) = ( 381 x 419 ) / 159639

= 381 / 419

= 381

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 381, 419, 840, 769 is 1
