Given numbers are 813, 781, 140, 465

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 781 are 11 x 71

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 465 are 3 x 5 x 31

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

Given numbers are 813, 781, 140, 465

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

Apply this formula for all numbers.

Step1:

LCM(813, 781) = 634953

GCD(813, 781) = ( 813 x 781 ) / 634953

= 813 / 781

= 813

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 465) = 465

GCD(1, 465) = ( 1 x 465 ) / 465

= 1 / 465

= 1

So, Greatest Common Divisor of 813, 781, 140, 465 is 1
