Given numbers are 445, 620, 478, 760

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 478 are 2 x 239

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

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

Given numbers are 445, 620, 478, 760

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

Apply this formula for all numbers.

Step1:

LCM(445, 620) = 55180

GCD(445, 620) = ( 445 x 620 ) / 55180

= 445 / 620

= 445

Step2:

LCM(5, 478) = 2390

GCD(5, 478) = ( 5 x 478 ) / 2390

= 5 / 478

= 5

Step3:

LCM(1, 760) = 760

GCD(1, 760) = ( 1 x 760 ) / 760

= 1 / 760

= 1

So, Greatest Common Divisor of 445, 620, 478, 760 is 1
