Given numbers are 280, 385, 111, 320

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 385 are 5 x 7 x 11

Prime factors of 111 are 3 x 37

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 280, 385, 111, 320

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

Apply this formula for all numbers.

Step1:

LCM(280, 385) = 3080

GCD(280, 385) = ( 280 x 385 ) / 3080

= 280 / 385

= 280

Step2:

LCM(35, 111) = 3885

GCD(35, 111) = ( 35 x 111 ) / 3885

= 35 / 111

= 35

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 280, 385, 111, 320 is 1
