Given numbers are 412, 403, 478, 840

The list of prime factors of all numbers are

Prime factors of 412 are 2 x 2 x 103

Prime factors of 403 are 13 x 31

Prime factors of 478 are 2 x 239

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

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

Given numbers are 412, 403, 478, 840

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

Apply this formula for all numbers.

Step1:

LCM(412, 403) = 166036

GCD(412, 403) = ( 412 x 403 ) / 166036

= 412 / 403

= 412

Step2:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 412, 403, 478, 840 is 1
