Given numbers are 438, 260, 947, 544

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 947 are 947

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 438, 260, 947, 544

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

Apply this formula for all numbers.

Step1:

LCM(438, 260) = 56940

GCD(438, 260) = ( 438 x 260 ) / 56940

= 438 / 260

= 438

Step2:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 438, 260, 947, 544 is 1
