Given numbers are 769, 455, 840, 765

The list of prime factors of all numbers are

Prime factors of 769 are 769

Prime factors of 455 are 5 x 7 x 13

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 769, 455, 840, 765

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

Apply this formula for all numbers.

Step1:

LCM(769, 455) = 349895

GCD(769, 455) = ( 769 x 455 ) / 349895

= 769 / 455

= 769

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 769, 455, 840, 765 is 1
