Given numbers are 403, 840, 813, 117

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

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

Prime factors of 813 are 3 x 271

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 403, 840, 813, 117

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

Apply this formula for all numbers.

Step1:

LCM(403, 840) = 338520

GCD(403, 840) = ( 403 x 840 ) / 338520

= 403 / 840

= 403

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 403, 840, 813, 117 is 1
