Given numbers are 891, 876, 545, 391

The list of prime factors of all numbers are

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 876 are 2 x 2 x 3 x 73

Prime factors of 545 are 5 x 109

Prime factors of 391 are 17 x 23

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

Given numbers are 891, 876, 545, 391

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

Apply this formula for all numbers.

Step1:

LCM(891, 876) = 260172

GCD(891, 876) = ( 891 x 876 ) / 260172

= 891 / 876

= 891

Step2:

LCM(3, 545) = 1635

GCD(3, 545) = ( 3 x 545 ) / 1635

= 3 / 545

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 891, 876, 545, 391 is 1
