Given numbers are 29, 13, 57, 90

The list of prime factors of all numbers are

Prime factors of 29 are 29

Prime factors of 13 are 13

Prime factors of 57 are 3 x 19

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

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

Given numbers are 29, 13, 57, 90

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

Apply this formula for all numbers.

Step1:

LCM(29, 13) = 377

GCD(29, 13) = ( 29 x 13 ) / 377

= 29 / 13

= 29

Step2:

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

= 1 / 57

= 1

Step3:

LCM(1, 90) = 90

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

= 1 / 90

= 1

So, Greatest Common Divisor of 29, 13, 57, 90 is 1
