Given numbers are 770, 828, 684, 765

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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 770, 828, 684, 765

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

Apply this formula for all numbers.

Step1:

LCM(770, 828) = 318780

GCD(770, 828) = ( 770 x 828 ) / 318780

= 770 / 828

= 770

Step2:

LCM(2, 684) = 684

GCD(2, 684) = ( 2 x 684 ) / 684

= 2 / 684

= 2

Step3:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

So, Greatest Common Divisor of 770, 828, 684, 765 is 1
