Given numbers are 480, 561, 638, 739

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 561 are 3 x 11 x 17

Prime factors of 638 are 2 x 11 x 29

Prime factors of 739 are 739

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

Given numbers are 480, 561, 638, 739

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

Apply this formula for all numbers.

Step1:

LCM(480, 561) = 89760

GCD(480, 561) = ( 480 x 561 ) / 89760

= 480 / 561

= 480

Step2:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

Step3:

LCM(1, 739) = 739

GCD(1, 739) = ( 1 x 739 ) / 739

= 1 / 739

= 1

So, Greatest Common Divisor of 480, 561, 638, 739 is 1
