Given numbers are 518, 420, 10, 803

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 10 are 2 x 5

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 518, 420, 10, 803

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

Apply this formula for all numbers.

Step1:

LCM(518, 420) = 15540

GCD(518, 420) = ( 518 x 420 ) / 15540

= 518 / 420

= 518

Step2:

LCM(14, 10) = 70

GCD(14, 10) = ( 14 x 10 ) / 70

= 14 / 10

= 14

Step3:

LCM(2, 803) = 1606

GCD(2, 803) = ( 2 x 803 ) / 1606

= 2 / 803

= 2

So, Greatest Common Divisor of 518, 420, 10, 803 is 1
