Given numbers are 835, 381, 645, 764

The list of prime factors of all numbers are

Prime factors of 835 are 5 x 167

Prime factors of 381 are 3 x 127

Prime factors of 645 are 3 x 5 x 43

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 835, 381, 645, 764

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

Apply this formula for all numbers.

Step1:

LCM(835, 381) = 318135

GCD(835, 381) = ( 835 x 381 ) / 318135

= 835 / 381

= 835

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 835, 381, 645, 764 is 1
