Given numbers are 765, 456, 212, 407

The list of prime factors of all numbers are

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

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 212 are 2 x 2 x 53

Prime factors of 407 are 11 x 37

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

Given numbers are 765, 456, 212, 407

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

Apply this formula for all numbers.

Step1:

LCM(765, 456) = 116280

GCD(765, 456) = ( 765 x 456 ) / 116280

= 765 / 456

= 765

Step2:

LCM(3, 212) = 636

GCD(3, 212) = ( 3 x 212 ) / 636

= 3 / 212

= 3

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 765, 456, 212, 407 is 1
