Given numbers are 765, 801, 970, 891

The list of prime factors of all numbers are

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

Prime factors of 801 are 3 x 3 x 89

Prime factors of 970 are 2 x 5 x 97

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 765, 801, 970, 891

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

Apply this formula for all numbers.

Step1:

LCM(765, 801) = 68085

GCD(765, 801) = ( 765 x 801 ) / 68085

= 765 / 801

= 765

Step2:

LCM(9, 970) = 8730

GCD(9, 970) = ( 9 x 970 ) / 8730

= 9 / 970

= 9

Step3:

LCM(1, 891) = 891

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

= 1 / 891

= 1

So, Greatest Common Divisor of 765, 801, 970, 891 is 1
