1, 13

GCD of numbers is the greatest common divisor

So, the GCD (50, 87, 90, 13) = 1.

Given numbers are 50, 87, 90, 13

The list of prime factors of all numbers are

Prime factors of 50 are 2 x 5 x 5

Prime factors of 87 are 3 x 29

Prime factors of 90 are 2 x 3 x 3 x 5

Prime factors of 13 are 13

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

Given numbers are 50, 87, 90, 13

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

Apply this formula for all numbers.

Step1:

LCM(50, 87) = 4350

GCD(50, 87) = ( 50 x 87 ) / 4350

= 50 / 87

= 50

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

Step3:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

So, Greatest Common Divisor of 50, 87, 90, 13 is 1
