Given numbers are 432, 642, 805, 891

The list of prime factors of all numbers are

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 642 are 2 x 3 x 107

Prime factors of 805 are 5 x 7 x 23

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

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

Given numbers are 432, 642, 805, 891

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

Apply this formula for all numbers.

Step1:

LCM(432, 642) = 46224

GCD(432, 642) = ( 432 x 642 ) / 46224

= 432 / 642

= 432

Step2:

LCM(6, 805) = 4830

GCD(6, 805) = ( 6 x 805 ) / 4830

= 6 / 805

= 6

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 432, 642, 805, 891 is 1
