Given numbers are 280, 105, 235, 497

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 105 are 3 x 5 x 7

Prime factors of 235 are 5 x 47

Prime factors of 497 are 7 x 71

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

Given numbers are 280, 105, 235, 497

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

Apply this formula for all numbers.

Step1:

LCM(280, 105) = 840

GCD(280, 105) = ( 280 x 105 ) / 840

= 280 / 105

= 280

Step2:

LCM(35, 235) = 1645

GCD(35, 235) = ( 35 x 235 ) / 1645

= 35 / 235

= 35

Step3:

LCM(5, 497) = 2485

GCD(5, 497) = ( 5 x 497 ) / 2485

= 5 / 497

= 5

So, Greatest Common Divisor of 280, 105, 235, 497 is 1
