Given numbers are 445, 740, 789, 630

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 789 are 3 x 263

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 445, 740, 789, 630

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

Apply this formula for all numbers.

Step1:

LCM(445, 740) = 65860

GCD(445, 740) = ( 445 x 740 ) / 65860

= 445 / 740

= 445

Step2:

LCM(5, 789) = 3945

GCD(5, 789) = ( 5 x 789 ) / 3945

= 5 / 789

= 5

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 445, 740, 789, 630 is 1
