1, 3, 5, 15

GCD of numbers is the greatest common divisor

So, the GCD (12, 43, 83, 15) = 1.

Given numbers are 12, 43, 83, 15

The list of prime factors of all numbers are

Prime factors of 12 are 2 x 2 x 3

Prime factors of 43 are 43

Prime factors of 83 are 83

Prime factors of 15 are 3 x 5

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

Given numbers are 12, 43, 83, 15

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

Apply this formula for all numbers.

Step1:

LCM(12, 43) = 516

GCD(12, 43) = ( 12 x 43 ) / 516

= 12 / 43

= 12

Step2:

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

= 1 / 83

= 1

Step3:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

So, Greatest Common Divisor of 12, 43, 83, 15 is 1
