Given numbers are 130, 819, 781, 940

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 781 are 11 x 71

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 130, 819, 781, 940

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

Apply this formula for all numbers.

Step1:

LCM(130, 819) = 8190

GCD(130, 819) = ( 130 x 819 ) / 8190

= 130 / 819

= 130

Step2:

LCM(13, 781) = 10153

GCD(13, 781) = ( 13 x 781 ) / 10153

= 13 / 781

= 13

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 130, 819, 781, 940 is 1
