Given numbers are 770, 407, 447, 664

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 407 are 11 x 37

Prime factors of 447 are 3 x 149

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 770, 407, 447, 664

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

Apply this formula for all numbers.

Step1:

LCM(770, 407) = 28490

GCD(770, 407) = ( 770 x 407 ) / 28490

= 770 / 407

= 770

Step2:

LCM(11, 447) = 4917

GCD(11, 447) = ( 11 x 447 ) / 4917

= 11 / 447

= 11

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 770, 407, 447, 664 is 1
