Given numbers are 814, 655, 306, 780

The list of prime factors of all numbers are

Prime factors of 814 are 2 x 11 x 37

Prime factors of 655 are 5 x 131

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 814, 655, 306, 780

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

Apply this formula for all numbers.

Step1:

LCM(814, 655) = 533170

GCD(814, 655) = ( 814 x 655 ) / 533170

= 814 / 655

= 814

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 814, 655, 306, 780 is 1
