Given numbers are 903, 980, 840, 223

The list of prime factors of all numbers are

Prime factors of 903 are 3 x 7 x 43

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Prime factors of 223 are 223

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

Given numbers are 903, 980, 840, 223

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

Apply this formula for all numbers.

Step1:

LCM(903, 980) = 126420

GCD(903, 980) = ( 903 x 980 ) / 126420

= 903 / 980

= 903

Step2:

LCM(7, 840) = 840

GCD(7, 840) = ( 7 x 840 ) / 840

= 7 / 840

= 7

Step3:

LCM(7, 223) = 1561

GCD(7, 223) = ( 7 x 223 ) / 1561

= 7 / 223

= 7

So, Greatest Common Divisor of 903, 980, 840, 223 is 1
