Given numbers are 505, 956, 781, 810

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 956 are 2 x 2 x 239

Prime factors of 781 are 11 x 71

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 505, 956, 781, 810

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

Apply this formula for all numbers.

Step1:

LCM(505, 956) = 482780

GCD(505, 956) = ( 505 x 956 ) / 482780

= 505 / 956

= 505

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 505, 956, 781, 810 is 1
