Given numbers are 903, 780, 756, 550

The list of prime factors of all numbers are

Prime factors of 903 are 3 x 7 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 903, 780, 756, 550

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

Apply this formula for all numbers.

Step1:

LCM(903, 780) = 234780

GCD(903, 780) = ( 903 x 780 ) / 234780

= 903 / 780

= 903

Step2:

LCM(3, 756) = 756

GCD(3, 756) = ( 3 x 756 ) / 756

= 3 / 756

= 3

Step3:

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

= 3 / 550

= 3

So, Greatest Common Divisor of 903, 780, 756, 550 is 1
