Given numbers are 170, 429, 765, 783

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 429 are 3 x 11 x 13

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

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 170, 429, 765, 783

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

Apply this formula for all numbers.

Step1:

LCM(170, 429) = 72930

GCD(170, 429) = ( 170 x 429 ) / 72930

= 170 / 429

= 170

Step2:

LCM(1, 765) = 765

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

= 1 / 765

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 170, 429, 765, 783 is 1
