Given numbers are 550, 840, 403, 945

The list of prime factors of all numbers are

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

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 403 are 13 x 31

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 550, 840, 403, 945

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

Apply this formula for all numbers.

Step1:

LCM(550, 840) = 46200

GCD(550, 840) = ( 550 x 840 ) / 46200

= 550 / 840

= 550

Step2:

LCM(10, 403) = 4030

GCD(10, 403) = ( 10 x 403 ) / 4030

= 10 / 403

= 10

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 550, 840, 403, 945 is 1
