Given numbers are 618, 503, 280, 120

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 503 are 503

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 618, 503, 280, 120

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

Apply this formula for all numbers.

Step1:

LCM(618, 503) = 310854

GCD(618, 503) = ( 618 x 503 ) / 310854

= 618 / 503

= 618

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 618, 503, 280, 120 is 1
