Given numbers are 645, 865, 882, 792

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 865 are 5 x 173

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

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

Given numbers are 645, 865, 882, 792

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

Apply this formula for all numbers.

Step1:

LCM(645, 865) = 111585

GCD(645, 865) = ( 645 x 865 ) / 111585

= 645 / 865

= 645

Step2:

LCM(5, 882) = 4410

GCD(5, 882) = ( 5 x 882 ) / 4410

= 5 / 882

= 5

Step3:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1

So, Greatest Common Divisor of 645, 865, 882, 792 is 1
