Given numbers are 765, 820, 57, 357

The list of prime factors of all numbers are

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

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 57 are 3 x 19

Prime factors of 357 are 3 x 7 x 17

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

Given numbers are 765, 820, 57, 357

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

Apply this formula for all numbers.

Step1:

LCM(765, 820) = 125460

GCD(765, 820) = ( 765 x 820 ) / 125460

= 765 / 820

= 765

Step2:

LCM(5, 57) = 285

GCD(5, 57) = ( 5 x 57 ) / 285

= 5 / 57

= 5

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 765, 820, 57, 357 is 1
