Given numbers are 379, 420, 790, 871

The list of prime factors of all numbers are

Prime factors of 379 are 379

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 790 are 2 x 5 x 79

Prime factors of 871 are 13 x 67

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

Given numbers are 379, 420, 790, 871

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

Apply this formula for all numbers.

Step1:

LCM(379, 420) = 159180

GCD(379, 420) = ( 379 x 420 ) / 159180

= 379 / 420

= 379

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 379, 420, 790, 871 is 1
