Given numbers are 124, 550, 403, 689

The list of prime factors of all numbers are

Prime factors of 124 are 2 x 2 x 31

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

Prime factors of 403 are 13 x 31

Prime factors of 689 are 13 x 53

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

Given numbers are 124, 550, 403, 689

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

Apply this formula for all numbers.

Step1:

LCM(124, 550) = 34100

GCD(124, 550) = ( 124 x 550 ) / 34100

= 124 / 550

= 124

Step2:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 124, 550, 403, 689 is 1
