Given numbers are 784, 732, 621, 445

The list of prime factors of all numbers are

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

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 445 are 5 x 89

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

Given numbers are 784, 732, 621, 445

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

Apply this formula for all numbers.

Step1:

LCM(784, 732) = 143472

GCD(784, 732) = ( 784 x 732 ) / 143472

= 784 / 732

= 784

Step2:

LCM(4, 621) = 2484

GCD(4, 621) = ( 4 x 621 ) / 2484

= 4 / 621

= 4

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 784, 732, 621, 445 is 1
