Given numbers are 781, 302, 72, 755

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 302 are 2 x 151

Prime factors of 72 are 2 x 2 x 2 x 3 x 3

Prime factors of 755 are 5 x 151

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

Given numbers are 781, 302, 72, 755

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

Apply this formula for all numbers.

Step1:

LCM(781, 302) = 235862

GCD(781, 302) = ( 781 x 302 ) / 235862

= 781 / 302

= 781

Step2:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 781, 302, 72, 755 is 1
