Given numbers are 145, 765, 831, 386

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

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

Prime factors of 831 are 3 x 277

Prime factors of 386 are 2 x 193

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

Given numbers are 145, 765, 831, 386

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

Apply this formula for all numbers.

Step1:

LCM(145, 765) = 22185

GCD(145, 765) = ( 145 x 765 ) / 22185

= 145 / 765

= 145

Step2:

LCM(5, 831) = 4155

GCD(5, 831) = ( 5 x 831 ) / 4155

= 5 / 831

= 5

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 145, 765, 831, 386 is 1
