Given numbers are 805, 630, 769, 385

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 769 are 769

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 805, 630, 769, 385

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

Apply this formula for all numbers.

Step1:

LCM(805, 630) = 14490

GCD(805, 630) = ( 805 x 630 ) / 14490

= 805 / 630

= 805

Step2:

LCM(35, 769) = 26915

GCD(35, 769) = ( 35 x 769 ) / 26915

= 35 / 769

= 35

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 805, 630, 769, 385 is 1
