Given numbers are 438, 365, 679, 664

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 365 are 5 x 73

Prime factors of 679 are 7 x 97

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 438, 365, 679, 664

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

Apply this formula for all numbers.

Step1:

LCM(438, 365) = 2190

GCD(438, 365) = ( 438 x 365 ) / 2190

= 438 / 365

= 438

Step2:

LCM(73, 679) = 49567

GCD(73, 679) = ( 73 x 679 ) / 49567

= 73 / 679

= 73

Step3:

LCM(1, 664) = 664

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

= 1 / 664

= 1

So, Greatest Common Divisor of 438, 365, 679, 664 is 1
