Given numbers are 445, 763, 120, 768

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 763 are 7 x 109

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 445, 763, 120, 768

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

Apply this formula for all numbers.

Step1:

LCM(445, 763) = 339535

GCD(445, 763) = ( 445 x 763 ) / 339535

= 445 / 763

= 445

Step2:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 445, 763, 120, 768 is 1
