Given numbers are 646, 332, 621, 765

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 332 are 2 x 2 x 83

Prime factors of 621 are 3 x 3 x 3 x 23

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 646, 332, 621, 765

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

Apply this formula for all numbers.

Step1:

LCM(646, 332) = 107236

GCD(646, 332) = ( 646 x 332 ) / 107236

= 646 / 332

= 646

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

Step3:

LCM(1, 765) = 765

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

= 1 / 765

= 1

So, Greatest Common Divisor of 646, 332, 621, 765 is 1
