Given numbers are 87, 89, 18, 83

The list of prime factors of all numbers are

Prime factors of 87 are 3 x 29

Prime factors of 89 are 89

Prime factors of 18 are 2 x 3 x 3

Prime factors of 83 are 83

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

Given numbers are 87, 89, 18, 83

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

Apply this formula for all numbers.

Step1:

LCM(87, 89) = 7743

GCD(87, 89) = ( 87 x 89 ) / 7743

= 87 / 89

= 87

Step2:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

Step3:

LCM(1, 83) = 83

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

= 1 / 83

= 1

So, Greatest Common Divisor of 87, 89, 18, 83 is 1
