Given numbers are 285, 203, 980, 803

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 203 are 7 x 29

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

Prime factors of 803 are 11 x 73

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

Given numbers are 285, 203, 980, 803

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

Apply this formula for all numbers.

Step1:

LCM(285, 203) = 57855

GCD(285, 203) = ( 285 x 203 ) / 57855

= 285 / 203

= 285

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 285, 203, 980, 803 is 1
