Given numbers are 445, 645, 860, 828

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 645 are 3 x 5 x 43

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 445, 645, 860, 828

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

Apply this formula for all numbers.

Step1:

LCM(445, 645) = 57405

GCD(445, 645) = ( 445 x 645 ) / 57405

= 445 / 645

= 445

Step2:

LCM(5, 860) = 860

GCD(5, 860) = ( 5 x 860 ) / 860

= 5 / 860

= 5

Step3:

LCM(5, 828) = 4140

GCD(5, 828) = ( 5 x 828 ) / 4140

= 5 / 828

= 5

So, Greatest Common Divisor of 445, 645, 860, 828 is 1
