Given numbers are 891, 133, 728, 651

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 133 are 7 x 19

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 651 are 3 x 7 x 31

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

Given numbers are 891, 133, 728, 651

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

Apply this formula for all numbers.

Step1:

LCM(891, 133) = 118503

GCD(891, 133) = ( 891 x 133 ) / 118503

= 891 / 133

= 891

Step2:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 891, 133, 728, 651 is 1
