Given numbers are 403, 790, 840, 480

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 790 are 2 x 5 x 79

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

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 403, 790, 840, 480

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

Apply this formula for all numbers.

Step1:

LCM(403, 790) = 318370

GCD(403, 790) = ( 403 x 790 ) / 318370

= 403 / 790

= 403

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 403, 790, 840, 480 is 1
