Given numbers are 19, 42, 83, 25

The list of prime factors of all numbers are

Prime factors of 19 are 19

Prime factors of 42 are 2 x 3 x 7

Prime factors of 83 are 83

Prime factors of 25 are 5 x 5

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

Given numbers are 19, 42, 83, 25

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

Apply this formula for all numbers.

Step1:

LCM(19, 42) = 798

GCD(19, 42) = ( 19 x 42 ) / 798

= 19 / 42

= 19

Step2:

LCM(1, 83) = 83

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

= 1 / 83

= 1

Step3:

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

= 1 / 25

= 1

So, Greatest Common Divisor of 19, 42, 83, 25 is 1
