Given numbers are 412, 660, 781, 823

The list of prime factors of all numbers are

Prime factors of 412 are 2 x 2 x 103

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 781 are 11 x 71

Prime factors of 823 are 823

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

Given numbers are 412, 660, 781, 823

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

Apply this formula for all numbers.

Step1:

LCM(412, 660) = 67980

GCD(412, 660) = ( 412 x 660 ) / 67980

= 412 / 660

= 412

Step2:

LCM(4, 781) = 3124

GCD(4, 781) = ( 4 x 781 ) / 3124

= 4 / 781

= 4

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 412, 660, 781, 823 is 1
