Given numbers are 280, 490, 169, 547

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 490 are 2 x 5 x 7 x 7

Prime factors of 169 are 13 x 13

Prime factors of 547 are 547

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

Given numbers are 280, 490, 169, 547

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

Apply this formula for all numbers.

Step1:

LCM(280, 490) = 1960

GCD(280, 490) = ( 280 x 490 ) / 1960

= 280 / 490

= 280

Step2:

LCM(70, 169) = 11830

GCD(70, 169) = ( 70 x 169 ) / 11830

= 70 / 169

= 70

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 280, 490, 169, 547 is 1
