GCD of numbers is the greatest common divisor

So, the GCD (15, 22, 39, 83) = 1.

Given numbers are 15, 22, 39, 83

The list of prime factors of all numbers are

Prime factors of 15 are 3 x 5

Prime factors of 22 are 2 x 11

Prime factors of 39 are 3 x 13

Prime factors of 83 are 83

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

Given numbers are 15, 22, 39, 83

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

Apply this formula for all numbers.

Step1:

LCM(15, 22) = 330

GCD(15, 22) = ( 15 x 22 ) / 330

= 15 / 22

= 15

Step2:

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

= 1 / 39

= 1

Step3:

LCM(1, 83) = 83

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

= 1 / 83

= 1

So, Greatest Common Divisor of 15, 22, 39, 83 is 1
