Given numbers are 545, 520, 285, 247

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 285 are 3 x 5 x 19

Prime factors of 247 are 13 x 19

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

Given numbers are 545, 520, 285, 247

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

Apply this formula for all numbers.

Step1:

LCM(545, 520) = 56680

GCD(545, 520) = ( 545 x 520 ) / 56680

= 545 / 520

= 545

Step2:

LCM(5, 285) = 285

GCD(5, 285) = ( 5 x 285 ) / 285

= 5 / 285

= 5

Step3:

LCM(5, 247) = 1235

GCD(5, 247) = ( 5 x 247 ) / 1235

= 5 / 247

= 5

So, Greatest Common Divisor of 545, 520, 285, 247 is 1
