Given numbers are 447, 485, 145, 140

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 485 are 5 x 97

Prime factors of 145 are 5 x 29

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 447, 485, 145, 140

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

Apply this formula for all numbers.

Step1:

LCM(447, 485) = 216795

GCD(447, 485) = ( 447 x 485 ) / 216795

= 447 / 485

= 447

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 447, 485, 145, 140 is 1
