Given numbers are 15, 59, 80, 89

The list of prime factors of all numbers are

Prime factors of 15 are 3 x 5

Prime factors of 59 are 59

Prime factors of 80 are 2 x 2 x 2 x 2 x 5

Prime factors of 89 are 89

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

Given numbers are 15, 59, 80, 89

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

Apply this formula for all numbers.

Step1:

LCM(15, 59) = 885

GCD(15, 59) = ( 15 x 59 ) / 885

= 15 / 59

= 15

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

= 1 / 89

= 1

So, Greatest Common Divisor of 15, 59, 80, 89 is 1
