Given numbers are 803, 728, 490, 979

The list of prime factors of all numbers are

Prime factors of 803 are 11 x 73

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 979 are 11 x 89

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

Given numbers are 803, 728, 490, 979

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

Apply this formula for all numbers.

Step1:

LCM(803, 728) = 584584

GCD(803, 728) = ( 803 x 728 ) / 584584

= 803 / 728

= 803

Step2:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 803, 728, 490, 979 is 1
