Given numbers are 13, 43, 73, 78

The list of prime factors of all numbers are

Prime factors of 13 are 13

Prime factors of 43 are 43

Prime factors of 73 are 73

Prime factors of 78 are 2 x 3 x 13

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

Given numbers are 13, 43, 73, 78

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

Apply this formula for all numbers.

Step1:

LCM(13, 43) = 559

GCD(13, 43) = ( 13 x 43 ) / 559

= 13 / 43

= 13

Step2:

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

= 1 / 73

= 1

Step3:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

So, Greatest Common Divisor of 13, 43, 73, 78 is 1
