Given numbers are 456, 891, 651, 445

The list of prime factors of all numbers are

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Prime factors of 651 are 3 x 7 x 31

Prime factors of 445 are 5 x 89

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

Given numbers are 456, 891, 651, 445

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

Apply this formula for all numbers.

Step1:

LCM(456, 891) = 135432

GCD(456, 891) = ( 456 x 891 ) / 135432

= 456 / 891

= 456

Step2:

LCM(3, 651) = 651

GCD(3, 651) = ( 3 x 651 ) / 651

= 3 / 651

= 3

Step3:

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

= 3 / 445

= 3

So, Greatest Common Divisor of 456, 891, 651, 445 is 1
