Given numbers are 546, 765, 891, 638

The list of prime factors of all numbers are

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 765 are 3 x 3 x 5 x 17

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

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 546, 765, 891, 638

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

Apply this formula for all numbers.

Step1:

LCM(546, 765) = 139230

GCD(546, 765) = ( 546 x 765 ) / 139230

= 546 / 765

= 546

Step2:

LCM(3, 891) = 891

GCD(3, 891) = ( 3 x 891 ) / 891

= 3 / 891

= 3

Step3:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

So, Greatest Common Divisor of 546, 765, 891, 638 is 1
