Given numbers are 515, 301, 781, 784

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 301 are 7 x 43

Prime factors of 781 are 11 x 71

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 515, 301, 781, 784

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

Apply this formula for all numbers.

Step1:

LCM(515, 301) = 155015

GCD(515, 301) = ( 515 x 301 ) / 155015

= 515 / 301

= 515

Step2:

LCM(1, 781) = 781

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

= 1 / 781

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 515, 301, 781, 784 is 1
