Given numbers are 766, 381, 412, 645

The list of prime factors of all numbers are

Prime factors of 766 are 2 x 383

Prime factors of 381 are 3 x 127

Prime factors of 412 are 2 x 2 x 103

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 766, 381, 412, 645

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

Apply this formula for all numbers.

Step1:

LCM(766, 381) = 291846

GCD(766, 381) = ( 766 x 381 ) / 291846

= 766 / 381

= 766

Step2:

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

= 1 / 412

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 766, 381, 412, 645 is 1
