Given numbers are 645, 784, 852, 877

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 877 are 877

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

Given numbers are 645, 784, 852, 877

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

Apply this formula for all numbers.

Step1:

LCM(645, 784) = 505680

GCD(645, 784) = ( 645 x 784 ) / 505680

= 645 / 784

= 645

Step2:

LCM(1, 852) = 852

GCD(1, 852) = ( 1 x 852 ) / 852

= 1 / 852

= 1

Step3:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

So, Greatest Common Divisor of 645, 784, 852, 877 is 1
