Given numbers are 816, 432, 190, 781

The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 190 are 2 x 5 x 19

Prime factors of 781 are 11 x 71

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

Given numbers are 816, 432, 190, 781

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

Apply this formula for all numbers.

Step1:

LCM(816, 432) = 7344

GCD(816, 432) = ( 816 x 432 ) / 7344

= 816 / 432

= 816

Step2:

LCM(48, 190) = 4560

GCD(48, 190) = ( 48 x 190 ) / 4560

= 48 / 190

= 48

Step3:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

So, Greatest Common Divisor of 816, 432, 190, 781 is 1
