Given numbers are 280, 375, 140, 817

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 375 are 3 x 5 x 5 x 5

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

Prime factors of 817 are 19 x 43

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

Given numbers are 280, 375, 140, 817

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

Apply this formula for all numbers.

Step1:

LCM(280, 375) = 21000

GCD(280, 375) = ( 280 x 375 ) / 21000

= 280 / 375

= 280

Step2:

LCM(5, 140) = 140

GCD(5, 140) = ( 5 x 140 ) / 140

= 5 / 140

= 5

Step3:

LCM(5, 817) = 4085

GCD(5, 817) = ( 5 x 817 ) / 4085

= 5 / 817

= 5

So, Greatest Common Divisor of 280, 375, 140, 817 is 1
