Given numbers are 280, 665, 503, 117

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 665 are 5 x 7 x 19

Prime factors of 503 are 503

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 280, 665, 503, 117

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

Apply this formula for all numbers.

Step1:

LCM(280, 665) = 5320

GCD(280, 665) = ( 280 x 665 ) / 5320

= 280 / 665

= 280

Step2:

LCM(35, 503) = 17605

GCD(35, 503) = ( 35 x 503 ) / 17605

= 35 / 503

= 35

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 280, 665, 503, 117 is 1
