Given numbers are 438, 430, 781, 736

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 430 are 2 x 5 x 43

Prime factors of 781 are 11 x 71

Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23

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

Given numbers are 438, 430, 781, 736

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

Apply this formula for all numbers.

Step1:

LCM(438, 430) = 94170

GCD(438, 430) = ( 438 x 430 ) / 94170

= 438 / 430

= 438

Step2:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

Step3:

LCM(1, 736) = 736

GCD(1, 736) = ( 1 x 736 ) / 736

= 1 / 736

= 1

So, Greatest Common Divisor of 438, 430, 781, 736 is 1
