Given numbers are 640, 738, 781, 743

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 781 are 11 x 71

Prime factors of 743 are 743

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

Given numbers are 640, 738, 781, 743

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

Apply this formula for all numbers.

Step1:

LCM(640, 738) = 236160

GCD(640, 738) = ( 640 x 738 ) / 236160

= 640 / 738

= 640

Step2:

LCM(2, 781) = 1562

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

= 2 / 781

= 2

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 640, 738, 781, 743 is 1
